What software do you use on the device itself? I recently got a Kobo Clara HD, but software support seems to be a big issue.

On one hand, there's folks using the vendor's OS, which looks like an abandoned custom-made Linux distro, where compiling anything is a nightmare. It's not really made to be hackable, but just to read books purchased via their partners.

OTOH, there's a near-mainline kernel, which works nicely, and hacking on the device becomes much nicer, but e-reader-oriented software seems to commonly rely on kernel APIs only present in the vendor's abandoned fork, and won't work on a more mainline Linux. But this is a great target for actually developing stuff.

I'm tempted to write my own minimal e-reader-focused DE, but honestly, I don't want another project on my hands and would like to use something that's already there.
