One of the top 10 extensions for Firefox and I like it a lot, but still some suggestions:

1. please give us an option to give saved sessions another background color in the tab list.
2. Put the saved sessions on top or alternatively give us a button to easily switch between "saved / collection" and "auto save".
3. We need an option to mark tabs in a session and move it / them within the session AND between sessions. Example: mark 3 tabs in auto saved session A and drag and drop them into session B or (most likely more practical) mark them, click on "copy", switch to session B and "paste" them.

Thanks!
