Well, is it like that using home manager?

I remember home-manager integrated with flakes being a nightmare for my potato laptop because I defined even the bash alias and such stuffs in it and even if I had to change/add a simple alias I had to rebuild the whole system lol, I could have just used home-manager standalone to be honest(I forgot to do this) but I just switched to using the old way of managing dotfiles with stow.

So right now I have it defined in the .config/sway/config file like this:

input * {
    xkb_layout "us"
    xkb_options "caps:ctrl_shifted_capslock"
}

Maybe I will come back to using standalone home-manager one day.
