@skjnldsv this one was hiding somewhere :D sorry for late reply:

• Loooks soooo great! Much better than the icons without labels we had before. You rock!
• The popovers should be centered (for the one in the viewer, should be to the right as far as possible with some whitespace, just like the user dropdown is). :) The left-alignment looks strange. ;)

@jancborchardt I think I remember, but did we not wanted to actually set the popover to center as default? 🤔

[jancborchardt]

@skjnldsv yes, you’re right! It definitely also seems that one of my most given feedbacks on popovers were to center them. :D So seems a good call to make that default.

Let's do that on the components then :)
