Some feature requests and questions - Lemmy.world

Are any of these features already existing (and can be activated, but I didn’t see how)? (1) Making the sub-lemmy in the header have a different color so the user can visually spot the topic before reading the title (2) Moving the header road footer, so see the topic/sub-lemmy after the title of the post (3) removing the exclamation mark in the sub-lemmy header across the app. Since it’s present in all sub-lemmy’s it is a bit a nuisance (4) change the size of the sub-lemmy names in the list of subscribed sub-lemmy’s Thanks for making a really awesome app!
