Well,
I can only speak for me, but I'm getting tired of your continous

I would buy that Mercedes-Benz if it offered a little more Ferrari
feeling

talk, Steven.
My answer: Then get yourself a Ferrari.

Remember, you're posting in a forum for free OSSN, and yes, the already existing functionality MAY BE enhanced by people like Daniel, me, and others. When we feel it makes sense, it's interesting and last not least: when we have the time to do so. And not because we would feel obliged in any way. We're no hired programmers in need to compete - we're just contributing in order to give something back to the originator.

Aside from that: I just built 'The Closer' an example on how to close the notification box.

I can only agree. this feature should be standard. I do not know any other social platform on which the menus must be closed similarly user-unfriendly. if i just want to quickly check my notifications as a user, i would like to continue scrolling and do not press the same button again. Unfortunately, I have not found a solution myself yet. the button for the settings already has this ability - just the other menus you have to close awkward on the button

No idea ... i don't see any advantage ...
If I intentionally open a formerly hidden section of a page by clicking an icon, why not closing this section by clicking the same icon again - instead of (mistakenly) clicking somewhere else on the page?

This will require surely a custom JS that will hide notification panel, again its bit tricky because anywhere in page includes those notification icons, the content of notification etc.

I also look for a solution to this problem.
