Right now, I can't show or hide all notes that are open in the desktop in a easy way.
Can be created another item group called "Desktop" different of "Recycle Bin", "Diary", "Search results", "Backup", "Favorites". The, you can mark the note with "Desktop", similar to mark the note as "Favorite". In this form, I could show or hide some group of notes that I want to be in the desktop.
The workaround that I use is to put the notes that I want to be opened in the desktop in the "Favorites" folder. But this is just a workaround because these are not my favorites notes really. But with this workaround I have another problem: I can not put a Diary Note as Favorite.
Thanks for all.
