Session manager and hibernated tabs Rated 5 out of 5 stars

This AddOn has served me well for years. I absolutely recomend it.
I only recently tried its session manager.
It has a nice range of features, but it doesn't use the hibernate feature when restoring a session, which is a problem when handling large numbers of tabs, which was the main reason for me to want to use a multiple session supporting session manager.
I'd love to see a fix for that.

This review is for a previous version of the add-on (0.4.0.3.1-signed).
