There are a ton of copycats of this launcher style on F-Droid (and likely more that aren't). They don't fit my usage style whatsoever.

The biggest drawback for me is the sheer number of apps I have both for work and personal use. This style of launcher requires that I'm always able to think of the name of the app I want every time, as opposed to finding them in the category folders I've set up. Even those that support categorization would require me to search 2x & probably still scroll (whereas currently I can open the app drawer and immediately open the category folder I want from muscle memory). With my aging brain (Gen X, and a life not lived in a manner most healthy for my brain function), remembering every app name is just not happening.
