It's not a huge issue, but I find just browsing my collection to find a read a lot more enjoyable on other ebook readers. IIRC there are plugins to add this feature, but it's not present out of the box.
On the few Kobos and jailbroken Kindles I've used it on, it also drains the battery significantly faster than the stock reader app, although not enough that I couldn't last at least a few days. On stock software I can go weeks between charges.
By the way, in the same settings I finally found how to set up KOReader to launch with a previously opened book. What a relief!
It's also great for jailbroken Kindles.
Paired with BookOrbit [0] and using plugins like BookShelf, BookEnds, and KOAssistant I have the best reading setup ever.
The speed of this on my Kindle is _insane_ compared to the stock software. I'm not talking about page turning, that was fine on both, but navigating menus is way faster.
It was a little finicky to configure but once I got a feel for it I didn't have a problem and 15 books read later since I installed it a few months ago and I never touch the settings.
My favorite plugins:
BookShelf: Best UI for viewing my books by author/series/etc IMHO. Much better than the Kindle default UI and much snappier
BookEnds: Configure the header and footer of each page to show what info you care about most. There are community configs you can test out easily and download right on your kindle if you like them
KOAssistant: highlight some text and throw it at an LLM with a provided prompt or your custom one. This was invaluable when reading the Hornblower series which used a lot of older english words/phrasing as well as nautical terms (which I'm completely unfamiliar with). I enjoyed the books way more since I could figure it out inside my kindle instead of constantly having to pick up my phone to look up a phrase.
BookOrbit: It provides a plugin for KOReader that syncs your progress, annotations, etc.
KOReader is table stakes for any e-reader I might consider. If my Kindle died tomorrow I'd have a Kobo or similar on it's way to me within hours. I won't use any reader that doesn't support KOReader after using it for these last few months.
This is the guide I used and it's up to date.
Seriously, takes ages to find specific settings for the first few times.
It has super useful features like the semi-auto-cropping which removes margins in PDFs (like papers or books), including unnecessary things like page numbers or similar, so that you can really maximize the size of the core content. It also has a nice chapter overview and other useful things!
Truly one of the best pieces of software I have used so far.

I finally got around to installing it as I got an xteink x3 and wanted to have cross device syncing back to my Grimmory server. Works great with OPDS and KOSync.
Although I miss using the native kobo sync where I could just add a book to my virtual shelf and have it auto sync to my device. OPDS seems very rudimentary in comparison, but it works nonetheless.
I've been slowly spinning up self-hosted services and Calibre was on my TODO. I haven't even heard of Booklore.
And then the UX… great project but could use a systems guy used to jailbreaking installations and a UX designer
Edit: for kobo at least
Worked fine for me.
