on-screen notifications

It would be really nice if wallabako could tell the user what it's doing. In Nickel, it pings the USB thingie to make it refresh its library, so the user has a (quite confusing) hint that something is happening, but in koreader and plato, there's no such thing, and it's really hard to figure out what's going on.

We should output something on screen. Ideally, we'd implement this natively, but I doubt it is that easy.

As it turns out, a koreader developer wrote FBink exactly for that purpose. There are go bindings but since it's in C, I doubt we can use it, as we then can't cross-compile to older releases. We could just assume fbink is present and use it if that's the case.

It would be a "power user" feature, but at least it would be something. We could link to instructions on how to install fbink, but unfortunately the upstream instructions are limited to "tinkerers and developers" which, granted, I'm part of, but it would be nice to just have KoboRoot.tgz in there for people to use... Update: this forum post seems to be the canonical place for that.

Update: fbink is actually shipped with koreader! it's in /mnt/onboard/.adds/koreader/fbink.

Anyway, just a thought for later!
