What is the name of the universal reader of almost all e-books? Kubunte was, but SUSE is missing?

Question

linux

the subject itself ... and I'm "delighted" with the design of the site, so I duplicate it - I installed suse .. and went nuts .. in Kubunte there was a universal reader for almost all books, well, it cannot be that it would not be in suse! remind me plz!
Narrowing everyone by default sends a writer in libre, it takes at least a long time to load, and in terms of garlic - not everything can
be done for critics - yes, I'm in sneakers, there are a lot of reasons. and there are reasons to try suzu... just to remember the name of the default, lightweight viewer, almost everything in the world, re-upload the system?... I'll still try to ask, thanks to everyone who responds ))
