Good Job! + Let Tabs move pls Rated 5 out of 5 stars

This addon is really essential for my work with Firefox. I usually start several new tabs when I search the web for certain issues and sometimes I haven't finished yet my searching about this theme and I start to search for second thing. And after a while a lot of tabs come together and with this addon I am able to get a quick overview over all tabs, so I can much easier and faster decide which tabs I can already close.
Anyways I think there could be still some improvements. If it is possible it would be very useful to handle the single tab in the overwiev in the same manner as it is used in Win Explorer with the thumbnails. This makes it much easier to move the tab from position to another. This function is for instance needed if u want to keep a particular tab open and want to position it next to the other tab of the same issue, but it is one of the first tabs and the other one of last. In this case you have to move the through whole tab bar and scroll it through there. If u have to do this several times and u got large number of tabs (~over 100) it is quite tiring.

It would also be nice to highlight the current tab u are in if u open the overview.
What do you think about making it possible to put some tabs together and let the user mark those together to a group? E.g.So that there different colors around different groups of tabs or like that. So that user can put them together and mark them. I don't know it's just a suggestion.
Keep up the good work! Thank you!
