The TAB system is very poorly optimized imo, its very complicated when you have multiple tabs to move a tab wich is in one end to the other, if you miss with the mouse and take it and put it back in it goes all the way back to the end, the tab system should have the possibility to group tabs, color them, and in the same way I use CTRL + TAB to cycle through them, there should be an easy way to move them up or down the line at this point, it gets quite frustrating specially with files that have long filenames, the tab takes de hole screen
