I would very much like to see an option to revert the width of items on the taskbar to 4.0.x behavior - I.E. if I have 2 two apps open each item/button on the taskbar gets 50% of the available width, if 3 items, 33%. The current fixed-widths of items leads me to have numerous items with titles that can't be destinguished from each other. Reproducible: Always Steps to Reproduce: 1. 2. 3.
I disagree, I thought it looked bad before and looks good now.
This was an aesthetic decision, and people have alternately praised and criticised it. I'd say try it for a while, and see if you get used to it. A pref is certainly possible, but it's up to someone else (Jasper? Olivier? Benny?) to approve or reject it, since I don't care enough either way.
I'm not going to add a preference for that, I'm sorry.
