I was hoping I'd get used to it as time went on but to be completely honest it's now been ~2 weeks and I'm still not liking how 'bubbly' it all is...Yeah, not a huge fan at the moment. It feels like quite a bit of wasted space due to the rounded corners and the lozenges housing icons in the Safari menu bar (for example).
Will no doubt get used to it (or find ways of removing/disabling it).
There's some good tips here though - https://eclecticlight.co/2025/09/15/appearance-matters-get-tahoe-looking-in-better-shape/
