This is 1.5.3 and the button situation is not at all under control 
I had to write a ton of CSS to fix the whole outline issue, and now that border default style is broken (Button Border Radius can not work - #5 by Claudio), my fix is broken as well and I have to override too many rules to get it work.
And this is absolutely not cool to have to do this on multiple installs…
No offense but I don’t understand how you can not take this more seriously.
1.5.4 should really be a button fix only update, please.
