To add to this, I find that if I click with MMB and then click outside the panel with the MMB it clicks the new popup immediately. Do you see that @brvdln ?
@CallumSykes @Gijs I noticed that if I click and the cursor doesn’t land over a command icon, the popup closes immediately. However, if the mouse cursor happens to remain over one of the command icons, the popup stays open. Please take a look at the video.
This is very handy. I’ll take another look into this. Sorry for the trouble!
