Running FG2 has always given me a problem with a cluttered screen and with the potential for a large number of menus and options to be open at the same time.
This can be very frustrating if you are trying to reference a particular screen but have to find it amongst the clutter of other items. This is particularly frustrating when it is the combat tracker.
Can I suggest that an 'Always on Top' functionality option is added to each menu opened? If not all menus, then just for the combat tracker?
