The defaults for hyprland are pretty good in my eyes, I've made some tweaks to the colour scheme, animations and even animated window borders but really its what you make of it.

Love using Hyprland, its minimal (which is a plus for me), no real issues outside of a sleep bug with my laptop when running hybrid graphics mode (amd igpu + nvidia gpu)

If you are not building your hyprland config from nix (as I am currently via symlinks) you can save the config file, and it will already be active allowing you to quickly test / amend / break all the things. For my config I need to rebuild the system, logout and login to see changes. Since I've been using Hyprland for a while now I've not needed to make many changes to the config so that works better for me.

I jumped from KDE to Hyprland, without having used a tiling window manager before, so adding all the necessary applications for things like brightness control, audio control was all quite a bit to take in from a full-fledged desktop environment.
