I love that someone is actively working on components in the python space. Coming back to python after years in the js ecosystem I've found templates really cumbersome to work with, especially not having type system support. I know there have been some attempts at JSX in python over the years but those projects all seem dead.
My advice to the OP, is to break out the component piece of the framework into a standalone lib that other frameworks can use. I think it'll be much easier to gain adoption that way.
I've found it's autocomplete really bad. It often hallucinates import paths and other illegal operations. It's not clear to me why it can't leverage the LSP better.
I just moved to the USA from Europe and have found sms/mms to be annoying. I'm consistently missing texts especially mms. Maybe my settings are slightly off or the payload is exceeding MMS size limits but it's way less reliable than Whatsapp. Everyone seems to use iPhones so they don't hit this issue until they text an android user like me.
I've been building up a vintage Fuji and have been using Sheldon's site to find data on old standards. It's been incredibly useful. On a similar note I've also used https://www.disraeligears.co.uk/site/home.html to look up derailleur specifics there is a lot of info there.
