I Lotus Notes there is an option:
Preferences -> Windows and Themes -> "On restart, reopen any tabs that were open when I closed the client".
This is a very good feature in Lotus Notes and I wish that it also would be available in Lotus Symphony 3
This is like an idea posted for Notes, but should apply to Symphony, too. When I've got multiple files open in Symphony I want a simple keystroke (such as Ctrl-Tab) to move among the files, rather than having to use the mouse to select which file to work on.
