Quake-style terminals have always been popular. I used to use Yakuake on KDE which was very convenient.
The convenience its not that those terminals open up with an animation (which is quite annoying). It was because there was a dedicated keyboard shortcut for them. You memorized that and you never ever think about managing the window of that application again.
So for years I have keyboard shortcuts assigned to my applications.
F1 opens Browser
F2 opens File manager
F3 opens Text Editor
F4 opens Chat App (Telegram)
F6 opens Email client
F7 opens ICR Client
F9 opens Terminal
F10 opens Music Player (Although Spotify on Linux has a bug that doesn't allow this to work)
Ever since I adopted this scheme I simply have a better quality of life during the time I'm using my computer. If there was a CPU usage for my brain, I'm sure its dropped. I strongly suggest you to try it out.
Because the shortcuts become muscle memory and you don't even think about them anymore. You know what you want and your fingers just know how to open it up.
I'm not quite sure which window managers allow this, but I'm using KWin and it allows me to arrange these shortcuts.
