Oh, this overlay is fantastic. It reminds me of how Feedly integrates with Reddit. You'd get an overlay very similar to this where you can read the post content, article, or be funneled to Reddit to make comments. Very neat and tidy. Feedly is what I missed most about quitting Reddit. Feedly doesn't have this sort of integration with Lemmy (yet), it just functions like a simple, but messy, RSS reader. This project makes me feel right at home and is such a quick and clean way to interact with Lemmy. Being able to post comments right in the overlay itself is even better than the Feedly/Reddit combo, too. Oh, and also the style for how comments are threaded is highly readable, it takes zero effort to understand or collapse comment chains.
I've mostly favored kbin (with a userscript) because I found it much easier to read and interact with than Lemmy, but your project is even better still.
The way it was explained to me was Fedora = RHEL Alpha, CentOS Stream = RHEL Beta, RHEL is Stable, then there are downstreams who build against RHEL. Only those who are downstream of REHL are effected by the changes. Both Fedora and Cent are necessary development platforms to support everything that eventually makes it down to RHEL in stable condition. They both depend on RHEL for funding, but RHEL depends on them for testing.
