This is allegedly "faster" but we're probably going to force all users to slow down, whether they realize it or not. Maybe enable an Accel-Click modifier to close tabs quickly (in addition to middle-click on non-contentLoadURL platforms). This would be faster/safer in both cases (closing and selecting).*** bugmenot - other : Other than the mouse click modifier, a right-click per-tab close button could also work (Maxthon uses this approach). We can also hide and disable the per-tab close button unless the user has pointed their mouse on the tab for a specified amount of time.* overflow Overflow bucket
