Honestly creating your own binds is so big

Hyprland has permanently changed the way I use a computer, pretty much everything I need on speed dial and opens/closes almost instantly

Also wrote a script to cycle through my audio devices and bound that to a button because I used to forever be fucking around with the gui every time I wanted to show someone a video on speaker or something

Just wish I could so the same on android
