First impression: Looks really quite promising as one would expect!!
However, some questions:
1) Created new 3rd tab (normally just use 2 tabs)...it already had some items in it's history...where did they come from? And history for existing tabs is already separated...did it track them before this release internally?
2) Created new 4th tab...the dropdowns show this tiny box with just a dash in it...would have expected them to just be disabled.
3) No apparent way to show global history with just touchpad...maybe a separate optional narrow arrow icon for globals that can be attached to back/next? Yes, right-click is avail but that's still unnatural for me.
4) When large nbr of items on history (45+), it overlays Windows taskbar and XY title bar...should/could it be limited to be within XY window only at bottom and have top at tabs as others do? I'd rather scroll than have my toolbars/taskbars hidden. This also blocks me from reclicking on arrow to hide the history as it's now behind history.
Addendum:
5) Any reason why bolding of current tab entries couldn't be standard even when HPT is not on? It would seem to make it easier even for those who don't desire HPT.
