VERY VERY good idea ... but unforunately until now too basic. I wish more options to control my surf time effectifly - and please be strict! Very first I wish to have the option to place the notification window right in the MIDDLE of my screen (not bottom rigtht), and also to have the option to set a RED coulor. Would also be great to have the following option: Set a specific time for a surf time after which a warning window says "Tab will be closed in 30 seconds", which I can only prevent by clicking in an time-extension button.

Is there a way to give the developer a personal feedback by E-Mail? Would be great!
