>One of them doesn't allow you to toggle, so you have create your own toggle script that kills or restarts it.
If you're not a fan of making scripts then sway (and wlsunset I assume) is not for you. My sway install is held together by a myriad of scripts - keybindings are handled by a script, starting programs via bemenu goes through a script, sway itself is started by a script, etc. That's just how this compositor and its ecosystem are designed - they're for people who want the software itself to do the smallest possible thing with the least possible assumptions so that the user can do whatever they want to fill in the rest.
