Well, the icons are just terrible, utterly insipid and lacking in power. It needs labels rather than icons, and better names for “zapper” and “picker” too (something like “remove elements from this page” versus “block elements from this site”).
I’m not sure if browsers apply height limits to these popups, but if not, almost every time there will be oodles of space for full labels and replacing the two single rows of buttons with columns. And even if scrolling is introduced, that’d still be better.
At least they now have tooltips - I remember when choosing "Advanced mode" (which you need for a lot of features) just disabled tooltips in the UI, on the theory that advanced users shouldn't need them! I (and likely many others) argued how crazy an assumption that was, that just because we understood how HTML and JS worked, we should remember a bunch of icons and what the dev decided they meant. Thankfully they were willing to listen and change the decision, and the UI is a lot better for it.
If you have some pull here, it would be really nice to have popups added to the grid in the middle of the dropdown where the colored boxes are. I use these very rarely and can never remember which column of colored boxes do what.
