Have two main tabs, one for Groups, one for Friends, when you click on the tab it opens up the list. When you click on a specific Group or Friend title it changes color....say blue, instead of green, and prompts it to come out of the tab list still be blue and be an active chat box, when you click on it again it goes back into the list of tabs. You can have a box pop up that asks if you want to open or close it . Also you could limit it to say having a max of 5 chat boxes open at the same time. As it is its a pain to find what your looking for, the list is long its all the same color....etc. Also a search box just for these contacts would make things MUCH easier as well. It simply needs to be reorganized a bit, so this is just a suggestion. Thank you for your consideration:)
