Save "Files currently being edited" as project

[nmpetkov]

The ability to sync when saving the open local files to the server is great.
However, I have to open 20 files sometimes and it works fine until the next day I have to open them again.
If the "Files currently being edited" screen has an option to save the currently open ones as a project under a given name, and then easily be able to load and open for editing and syncing, that would be a big step for Filezilla fans, combined with text editor, for example Notepad++.
