Thanks for the feedback, this is what I was hoping for.

> Scrolling up should stop auto-scroll in the chat

This is at the top-of the list for today, check the website/discord/twitter for updates. I want to do both - pin the button at the bottom, and also make sure that if you scroll, it will stay there. Currently, it's one component which contains the button and also scrolls and it was a bad idea.

> Blurring the window while installing

Agreed 100%, I definitely want to improve downloader a lot more but this was good enough for first release.

> Maybe an uninstall button for models is appropriate.

It should be there (in the upper area), I hope the 24h cache in cloudfront is not too much but the link should be pointing to 09-18 version which has Delete button.
