I noticed an edge-case UX bug in @MonaApp: If the More menu (the ellipsis icon) is close to the alt text button in an image, hovering over the latter highlights the former. And clicking actually opens the More menu. As a result, it's impossible to read the alt text. (Resizing the window is a valid workaround.) Not sure if this appears in Mona 7 as well, but I thought it was worth making you aware of.
