When multiple instances of the same application are opened, they get grouped on the panel. When I click on the grouped tab, it gives me a small list. Wouldn't it be more usable if clicking on a grouped tab gave out slightly bigger things, maybe similar to the thumbnails displayed when one hovers over a regular (non-grouped) tab?
I just realise that I get exactly what I want when I hover over a grouped tab. Could you make it display the same thing when clicked? That will make it much more usable.
