After reading that this was inspired by Emacs I thought I would give it a go.
Sadly my enthusiasm lasted perhaps a couple of minutes as I got a dialog saying "The editor is not responding. Would you like to force close it or just keep waiting?" when I tried to open a file. Assuming user error I persisted, loading a different file finally. Not impressed with the text highlighting colours I thought I would change the theme. Took me ages to finally figure out how to select one of the preloaded themes from the list. A short while later when trying something else I again get the "The editor is not responding" message.
Think I'll stick to Emacs for now.
