Seems good, I like it. I might try it later on my server (hopefully it's not too heavy on the system, since I'm going to try it in a small vps).

But it's still another reader that I'll probably not use. Why? Because since there isn't an open standard for RSS reader I can't use it with the client I want.

I'm not saying it's your fault, as it sure isn't. But it's sad that we didn't learn this from the death of Google Reader. There were some talk about creating an open standard right after it's death, but nothing major came out of it.

This is also why I'm still using Google Reader, because every RSS reader out of there doesn't have either a mobile client or a website that I like. If there were an open standard, I could use the mobile client I want, the desktop client I want, and rely on the backend for synchronization and reading on computer without a desktop client.
