Well I guess that depends on what system is your "first" ;) I definetely feel more at home on Windows, but I have a lot of respect for people who use Linux as a primary system.

Ok then I will merge this request into that one, this way you'll get a lot of votes :)

Glad you liked it! But still will have to wait a bit I'm afraid

Thanks a lot for the suggestion! Please note that you don't have to close the note editor to open the next note, you can simply go back to the notes list and double-click the next note to edit it. 

Thanks for the suggestion! Will definitely consider adding this as an option for V4

It's planned. However note that this idea here talks about clipping, so it will make CN into a kind of scissors tool.
