I'm so excited for the "turn website into app" feature of the next macOS. I do that for JIRA, Github, and Gmail (when I used it) and it's so nice to get that clutter out of Safari and into the app switcher. Up until now it's been a bit of a hack to make it work well (somehow still using Fluid to make the app, and using Choosy to make links mostly work) it's actually been something I've been considering building a good solution for because the existing ones are so bad. Yay!
