the font size thing is good tho it'll really annoy the 'more characters' folks who can now visualise where all the text they're not allowed to write would go
i’m for it in theory but in reality i already have to scroll down and up on my phone to compose, check he quote post or write alt text, check character count when the post button goes grey, etc
well it like typographically emphasizes the focused post versus its replies & context so idk if u want to throw it out or not. but the post font size is not uniform all the time is all
