I have been spoiled for customisation by hyprland recently and have been looking at customizing my phone UI
All the custom launchers I've tried so far are rather lacking in customisability, features and are usually paywalled for "advanced" features like having more than one widget
At the moment I think I'm going to end up back on the default one
Depends on how many applications you have I guess, I keep my number of applications down, so the amount per letter is at max like 5 or 6, so searching doesn't take a long time at all
