Charmstone (Paid) The quicker switcher launcher for macOS, same as Rcmd. Just another choice I guess. Source: over 1 year ago

Not exactly what you are describing: Charmstone. Source: over 1 year ago

Charmstone [1] is a different take from everything mentioned here (I'm the developer). The idea is to use your spatial memory to switch/launch apps faster than anything else that I've found, with a smaller learning curve and less memorization. You can use keyboard shortcuts with the arrow keys, modifier keys + cursor movement, or a trackpad gesture. [1] https://charmstone.app. - Source: Hacker News / over 1 year ago

Have you tried Cario-Dock? Its not a native KDE app, but it does support KDE integration. I installed it on KDE Neon after the Latte Dock announcement. No crashes, and it has a lot of features. Source: over 1 year ago

If you like Macs, the dock program Cairo-Dock has a bunch of built in themes, including one to look like the OSX style dock with the cool reflections: https://glx-dock.org. Source: over 1 year ago

The closest thing you can do this is with cairo dock. It take some time, to customize it to make it look like what you see in the picture. It was a trend a decade ago, but not sure how much the package is maintained right now. For alternative you can check out docky which works pretty well with Gnome and its cousins, and if you are using KDE I better advice you to stick with latte dock. Source: over 2 years ago
