It has an RSS reader, Wallabag integration, cloud storage integration, a Lua plugin API... but it can't open DRM'd ebooks. This is what's frustrating about DRM for me: it restricts the software you can use to only software from huge corporations. Want to make a small tweak to your reader? Nope, you're not allowed. I only buy ebooks when I can find a DRM-free source for them, which pretty much means Tor/Baen/Humble/etc. I could buy DRM'd books and strip the DRM, but I'd rather not support the practice; I'm more likely to buy a physical book in that case.
