What happened?

I'll add here all the problems (mainly UI related) I've found after updating to 1.7.5b:

• The menu icons in the tabbar are smaller than the tab buttons, which is (imo) very ugly
  
• The new home icon looks more like a mail than a home
• if the top bar is set to hide there is no gap between the end of the bar and the back arrow button
  
• The spacing between extensions in the topbar is too big (not sure if it was like this before, I think not but not 100% sure)
• I don't understand the existence of the scrollbar like it is right now: the only reason for its existence is if for x reason you can't scroll the tabs in any other way so you should use the scrollbar. I say should because if you try to do that you drag the zen window around, making the scrollbar simply useless. Is it possible to make it clickable (I know there is a mod for it, but this should not be reliant of 3rd party to work) and add an option in look and feel to disable it? (meanwhile, do someone know how to remove it using css?)

Reproducible?

• I have checked that this issue cannot be reproduced on Mozilla Firefox.
