I'll have to look into that, my two halves are never more than a couple feet apart, and always with LOS, so I should be able to get away with pretty low power.
It would be cool for it to also display some info, like the current layer of the keyboard, battery percentage on wireless.
It would also be neat if it could take some contextual info from the computer to display things like playing media, or notifications, but that seems like it would be pretty arduous to implement.
My rotation only has me working 2 or 3 days at a time(GF is on the same schedule, so I prep her meals at the same time as mine), so typically the night before one of those working periods I'll make an extra large dinner that also serves as my meal prep.
I have maybe a dozen dishes in the "frequent rotation", but I regularly cook off menu as it were. This last work period I make is burrito bowls, and we've got a 3 day coming up, not sure what I'll make yet, but I'm currently feeling curry rice.
I've been running Vaultwarden for while, and it's great, love not relying on 3rd party for my backend.
