Most fun is when the menu opens both on button hover and on button press, but if the menu already opened, clicking the button closes it instead, so the first 2-3 you use it, you end up opening the panel and closing it immediately.
Not sure how stuff like this gets deployed in the first place, guess we're just a few people left who test things we develop before we push them to the public, I'd rather believe that than that people just don't care anymore...
I feel like the modern web/app ecosystems have forced developers onto a red queen type treadmill, so software never really matures. They often build up to 70% of the features they want, the codebase gets intractable because of all the crap they have to deal with and they start over.
I love software like Gimp, Blender, Inkscape, etc, that matured over decades and kept their soul.
