Nixnote2 have 500 downloads per day or 182.000 downloads per year so there is a market for Evernote for Linux which will be much larger if there where a native Linux client. Nixnote2 have some bugs that makes it irritating to work with. I am a paying Evernote customer and consider to cancel because of a lack of a linux client or support for Nixnote2 or running Evernote on Wine which does not work well either.
Have the Window title change into the title of the note you are working on. Example: I work on a note called 'Week 52' but the Evernote window (in windows) is called 'All notebooks - <username> - Evernote' instead. I believe this is not compliant with the MS Windows standard and it should be fixed.
