@zauberfritz Well, I just counted my history items again... First of all, there is a weird thing going on... I see the history up to a point (about 100-120 items), but if I open one or two grouped items in the history, suddenly more history items become available at the end... But again, limited... I counted about 300 with all grouped items expanded, and as before, every new tab I open, the last history item is removed, which means the number is fixed and I have reached the limit.
A "select all" and "delete selected" would be greatly appreciated, especially when you search the history for a specific site to remove. As you said, search all google.com, then select all, then delete all selected... It's weird to have to click the X one by one...
The thing is that, with this limit, history becomes partially useful, or partially useless, depending on the perspective...
