Hi,
When mouse hovering over the action items on the Toolbars & menus section, I've noticed there's an automatic resizing going on at the lower part of the dialog. This only happens when the item description takes two lines. Not sure if that's a glitch? Perhaps adding more vertical space before the "line" containing the buttons Restore Defaults, Cancel and Apply would prevent it.

I was actually checking if there's now a way to add some secondary plugin actions to the toolbars, but I'd seen this resizing occur in previous versions.
