Hang in There, Kogasa-san 3419
I'm using a smartphone app called BLYNK, but that's just about all the functions you can on the free-to-use version. There are in-app points called "ENARGY", and these are used up something like X amount per button and X amount per display. You get 2000 points for free, so I made do with those. It isn't that expensive, so I'm buying about 20,000 points. :-) And there's a Conscience setting that returns points to you when you delete functions!
I've already sent the device to Patchouli-san, but it seems they haven't installed it yet, so I don't know how user-friendly it is. :-)
