An idea I had is in regards to the New Gmail design that allows Add-In to be displayed on the right side of the Web Browser window which I think would be a great opportunity to make an Evernote Add-In similar to the Google Keep and Google Tasks.
I have a bug to report. Whenever I open Evernote after it has been fully quit, Notes from Various Notebooks will appear back into my default Notebook. I will then put them back in their respective notebook and then they will reappear in the Default Notebook the next time I reopen the app. I haven't found any connection between the notes but it is usually the same 4 notes that keep appearing back in the default notebook.
