I installed the last nightly build on my Sage. Tried out of curiosity a manga, cbz format.
And I’m so excited, it’s so fast! Nothing compared to the stock software! Love it.
Only downside is when I exited Koreader, my Sage went on a loop, trying to connect to the computer, restart, trying to connect to the computer….
I had to manually reset it.
I’ll wait for the stable release.
