As much as I like the feature, the plugin is buggy as hell. It sometimes forgets the tabs in a specific container for a time, then all of a sudden opens them up. Any subsequent opening of said container then doubles the tabs that were opened... The only remedy is to delete the container and recreate one. At which point we start again. For some reason this only happens on a few containers and never on others, so the plugin is still usable albeit frustrating.
