Great, but buggy Rated 4 out of 5 stars

It's very good at what it does, however there are a few bugs to note:
1) When moving too many tabs around, black "tab bars" start appearing everywhere and it becomes impossible to organize anything without a restart.
2) Sometimes the program "freezes" tabs; you cannot close them by clicking "x" and right click has no effect. It is persistently amongst any tab that is considered currently active. As well requires a full restart.
