Idea

Would it be possible to add border hiding on unit frames and action bars? I've tried Borderless and it doesn't seems to work with EditModeExpanded.

Solution

Try to describe the solution you are aiming for

Optional Context (e.g. Screenshots, Scribbles ...)

Fair enough. Thanks for recommend; I'll give it a go!

Just did a little bit of checking - what I'm looking for is removal of the button borders and the droplet shaped border on the unit frame portraits.

I have no plans on adding this currently. Personally i use HideActionBarBorders for the actionbars. This won't fix the problem with the character frame though.
