I really like this extension a lot and being able to separate my work/personal/school stuff into different groups, and being able to pin frequently used sites as tabs is awesome. But I do have one big gripe, which is that whenever I have to close or restart my browser for any reason, and I go to reload my last session from my Firefox history, all my tabs end up in the "Other" tab group and I have to drag them all back into their proper groups.

I'm not sure if there's some setting I have wrong or that I didn't enable or what, but it's a major annoyance and hassle, especially being someone who often has 50 or more tabs open at once most times, as I don't think I can select and drag multiple tabs at once in the group manger and have to do them individually. I'm glad all my tabs are saved and all, but I feel I should be able to reload them WITHIN their actual tab groups.
