[creality]

Hello,
I use overdrive to borrow books from my library directly to my Kobo. Is there a way to access this through Koreader?

As a corollary, is there any way to access my collections from within Koreader? I have spent a large amount of time arranging tags in calibre and now it seems like I might have to go back to good old folder based library (as opposed to tags/collections based).

Is there any trick to access these collections easily from within Koreader? And to be a little greedy, make this the primary mode of navigation in Koreader?

Sorry if my question comes off as stupid. Brand new user.
