Also! That's so awesome that you're one of the maintainers for uBar!It's become one of my favorite apps to use in recent years. One of the few apps I haven't minded throwing money at lmao. I'm honestly surprised it's not more popular than it already is. Everyone seems to just use cDock, which I never really liked. Odd, though. I did love RocketDock which is very similar once upon a time haha. I just really like the overall seemlessness of uBar. (And how easy it is to use and edit.) I just wish they'd implement a way to move the icons around a little bit easier. Like dragging them similarly to the regular dock.
The Übersicht player you mentioned you made, is it just for show then? Since the buttons don't seem to work? I've been trying to make something that works with both Spotify and iTunes that will actually match my desktop. I'm never quite satisfied with the colors;; It's been fun messing around with though.
Bowtie seems to work fine for me? I just did the Mojave update last night (Curiosity murdered my desire to wait on dark mode lmfao. Too many old HUD-feels.). I tried to open it, it asked if I wanted to allow it to run and I clicked Allow and it seems to be working just fine. I think I have elevated permissions on this account though, so it might be because of that? (I got real tired of disabling/enabling Sip any time I wanted to change an icon;;.) I'm sad to see that Liteicon doesn't seem to work with Mojave yet... My only real complaint so far. So now I have to go and edit the Finder/Trash icons one by one myself if I want to change those out. Which I mean, is fine, I can do that, it's just annoying when it was a two-click process before lol.
I've tried Supernerd in the past. Wasn't really a big fan of it. Nothing particularly wrong with it, it just didn't really work with my work style very well. And also, like you mentioned, the setup was a big pain. xD It (and Pecan from what I can see in screenshots) certainly look nice. But it's a bit too minimal for my tastes. I love the look of stuff like that, but in my actual day-to-day use, I prefer to have things a bit closer to the standard MacOS experience. Easier reaching distance for things I use~
SoundAr sounds really interesting though! I'm going to check that out! I do miss the days of sounds popping up here and there on my machine. I had added tons of old .wav sounds to one of my older macs so I was able to have things start up with sounds and iChat would have different sounds, too. ;w; I miss that.
