Yes.

No but might be developed in the near future.

No, not at all.

No, not at all.

No but then it will after a few weeks, work as a viewer only.

Yes you can. When you download docfreak there is always an active license in it that will work for at least 14 days and allows you to do anything with the content.  After a few weeks, you can only view (not modify) thecontents until you buy a (one time purchase or subscription per year) license. Therefor you can always use docFreak as a viewer without a license.

docFreak will then act as a viewer (you can view but not edit the content).As a viewer docFreak is free of any charge.

Then you will be able to add and modify content again.

Yes you can. The default docFreak file is called docFreak.dfdoc.  You can rename, copy and move that one to any name you like as long it has the .dfdoc extension (and.... not to a name with spaces in its name or folder name).

Yes you can. Copy with your file manager (like Windows Explorer, Linux Dolphin or macOS Finder) the docFreak.dfdoc to any other name you like (without spaces in its name).

Even with the same license?
Yes.

Yes you can. Use the Create empty DB option from the main menu.

Copy with your file manager the dfdocinit.dat file to a file name with a name of your choice (again without spaces in its name) and give it a .dfdoc extension. Example:to create an empty db with built-in help use your file manager to copydfdocinit.dat to MyNewEmptyToo.dfdoc

Yes and no..... Create the folder inside another folder first (for example inside the New folder) and drag the just created folder to the root/top level.

Yes, you can (as deep as you need).

Yes, you can: create folders with levels, move, remove, copy and shortcut tree items/folders.

Save your changes/edits by a RIGHT mouse click on the tab handles (then select Save).You can also press Ctrl-S  or Cmd-S to save all tabs at once.

Yes you can. You can even create styles to format text with a mouse click.

Use your file manager to select 1 or more files and drag them to the tree.  The files are then copied into your docFreak automatically.

Yes you can export as Word, Writer, Pdf, Html and markdown.

Yes but only if you drag them to the tree first.

Yes you can. When you select images they are inserted into the editor and shown as an image. When it contains office files then they are inserted as a link into the editor. Due to a bug it is better to drag the files to the tree first and from there to the editor (the regular text color is then restored).

Note: everything you drag is copied into your docFreak and then shown in the tree.

Insert(drag) as much as possible from the tree to the editor because that way the text afterthe link will have the normal text color.If you create a hyperlink by a drop operation from your file manager, the hyperlink color might affect the text thereafter. You can prevent the hyperlink color affecting the text thereafter by adding additional spaces and position the cursor in front of the extra spaces before you drop from your file manager.

Keep in mind that it might look that it points to a Word file but in reality it loads the copy of that Wordfile from your docFreak db into Word. So it will open Word for you. When you make changes to the Word document, it will be noticed by docFreak.This way you can docFreak use as a launcher of all kind of files.

If it is a native docFreak document or note, it is opened and shown inside a tab of docFreak. If it is something else like Pdf, Excel or Word (for example) then it opens the correpsonding program for you.

docFreak will use the multi-media player installed on your OS. If you did not install a media player, install one of your choice.

docFreak needs to be installed into your Home folder like /home/JohnDoe. Start a cmd line terminal and run ./setup_docFreak and follow the instructions. You can trouble shoot the starting of docFreak by starting ./docFreak.bin from a cmd line terminal like: cd $HOME/docFreak; ./docFreak.bin.  It might show error messages that give a clue about where to search for.
Also... check the content of docFreak.desktop file. That one is used to start docFreak from your desktop. You can also edit that one to change the location where you want to start docFreak from (but you should be familiar with basic Linux commands).

docFreak needs to be dragged to your Home folder (press Cmd-Shift-H to open your Home folder like /Users/JohnDoe) and drag docFreak to it. From there you can start docFreak.

Select on or more tree items you want to be removed and press Ctrl-D. The built-in Help suggest that you can use Ctrl-Y but that does work only inside the editor.

Select the line you want to delete and press Ctrl-Y.

Select the tree item you want to add keywords or tags to.Press Ctrl-Shft-K, a new tab is displayed.Hover your mouse just above the Add tag button, an input text field will light up.
‍

Enter your keyword, tag or keyword/tag phrase in it.Press the Add tag button. Repeat if you want to add other keywordsPress Save to activate all added keywords.
‍

Press the listbox (between the Delete and Save button) to show all keyword tags.

Be sure that your docFreak uses the OS environment where it runs on. Follow these one time only steps: Check the Settings, Setup -> OS environment tab, press Set defaults for OS and after that Save. Next go to the Fonts tab and select your default fonts and press Save. The fonts you select here are connected to the DF and MF buttons.

Then create the style you want, Go to the Styles tab and be sure that you have the following Style names (by default they should be there):
H1 (Header1 style settings that is connected to H1 button)
H2 (Header2 style settings that is connected to H2 button)
H3 (Header3 style settings that is connected to H3 button)
where H1 is the biggest header style and H3 the smallest header style (but still a bit bigger then regular text).

If you do not have them, create them (use the New button) as H1, H2 and H3 (do not use other names yet). When you create a style it is upmost important that you select ALL text inside the style preview (the box below the Hyperlink text color and Hyperlink background color).

Use the format options (Bold, Italic, Underline, font name and font size boxes) and the options inside the Style tab itself to format the preview.  

Press Save, the Style is saved.

Repeat this step for other styles you want and keep in mind that the Preview text must be selected each time you create a style.  Note that the preview text can by anything as long as you select ALL text inside the preview and as long you use the format options of docFreak to format the style.

The best way to experience this luxury and comfort is to download docFreak (no need to register) and try.
