Personal opinion: the colors are super ugly … This aside: The reader generally seems to work. But some things didn’t.

It wasn’t able to find feeds on github release pages and it wasn’t able to sync with YouTube subscriptions. Both likely due to the old age of this extension.

Also, the popup that shows the feeds looks so crammed, there also seems to be no way to see already read feed items. They just disappear.

I love the look and feel of the UI, but could not actually import my feeds from another service - nothing happened after selecting my file.
