I would like to ask you if it's possible to add the "undo"/"redo" command in the editor. If accidentally delete a piece of text I cannot have it back even if I press the usual CTRL-X, and this is very frustrating. Thanks.

Currently the undo/redo function is only available via the popup menu. Right click anywhere in the text box and choose Undo or Redo. The shortcuts Crtl+Z and Ctrl+Y are not working, I will see if it is possible to reactivate them.

I reactivated the functions and I took the opportunity to also put the corresponding buttons. It will be available with the next pre-version.

Great! Thank you so much!

Check the site regularly, I plan to publish the next pre-version next Sunday.
