The summary of Thunderbird basically.. It has like all the features imaginable, and the core ones are done ok-ish, but after years of using it I still feel like throwing it out every now and then because of all the weirdness and quirks and straight-up bugs.

Agreed. It's also nice to have the ability to search everything, I sometimes forget where I read something.

One thing I wish it could do is take a standard web page (HTML) and allow me to build a feed out of it. Or at the least keep any eye on the page and tell me when it changes.

It is perfectly acceptable to me that neither functionality is easy to work with, because in return I get all my non-instant messaging in just one application.

I'd probably really like it if it was possible to interact with WhatsApp and possibly Slack inside Thunderbird as well.
