Thanks for testing it guys
Fullscreen support is easy to implement, I just have to decided if after pushing the fullscreen button all Conboy windows are fullscreen or only the one which is currently active. What do you think?
The support for undo will probably take a bit longer as it is not completely trivial

For the next version I'm planing:

• Complete editing of nested bullet lists
• Clean up the UI
• Automatic link creation while typing

And of course the fullscreen support, once the decision is made how it should work...
