I am personally very much not a fan of the way dropdowns and buttons highlighted. I don’t like the fact that it’s using these weird glowy outlines. This may be the design language but it’s not to my liking.
I think it would be a good idea to allow changing the highlight outline and fill of these widgets via color schemes so that the user could get a solid highlight on mouseover or click. I want these to just be solid blue for example and I’d like to be able to configure that style via color schemes.
