Style changes after UCP

The new move to UCP and MediaWiki 1.33 isn't as bad as it seems. However, there are some things I'm willing to change if I can.


 * The "Add Category" button is too big and too dark for its position.
 * Perhaps a change of color, downsizing, and replacing it's content with a plus (+) would work.
 * The editing box is too narrow height-wise. There is no option to collapse or move it. This will be an issue when attempting to navigate.
 * Table under 'File history' on file pages has a horizontal scroll, ew (, intentional or incase?)
 * and  have no bottom padding, used to be 3px.
 * Edit count on Profile is much too small, (, increase font-size and decrease margin)
 * Transition on Admin Dashboard feels off, there's two transition properties, one under  and the other on
 * Plainlinks class needs to be added:
