Plato Document Reader for Kobo E-Readers

Why would I use this over Koreader which:
* runs great on potatoes like K3W and Kobo touch C (and any Android or Linux system)
* has OPDS support (search and pull books from a calibre server)
* uses the same mupdf library
Edit: Found the issue, it's under consideration: https://github.com/baskerville/plato/issues/69
