The config is also split up into usr/share directories, too, if I remember correctly. I installed Manjaro sway on my laptop to get and Arch-based OS with sway on it installed quickly. Then I tweaked it to my liking over a few months and wanted the same setup on my desktop.
It was a pain to transfer the config over to say the least, and then all the pixel perfect alignments I had done in waybar we’re broken on my desktop anyway.
OP is better off putting together a new sway config from scratch, using the Manjaro install for reference if possible. Maybe spin up a VM to have both at the same time easily?
