Incredible how middle-of-the-road this extension still is after all those years of development...

MEMORY REDUCTION: yes, it can help you save memory... But a tab suspender does that equally well.

SESSION MANAGEMENT: well... VERY disappointing for that. On the OneTab Page you cannot move tabs to another window. You can't even rearrange windows.... Pretty useless for anybody who wants the tiniest amount of control over his "sessions".
