I know this is an area of personal opinion, personal taste, and what I got used to with old Bear, so everyone won’t be satisfied. But I want to voice the feeling.
The new big h1s change how Bear feels to use for writing. For me, my Bear notes aren’t blog posts and they aren’t GitHub readmes, those are for other people to read. My notes are for me to read and reference.
The new h1s take up a lot of room. The increased font size and padding mean fewer words fit per line now so lots of titles will wrap now, which makes them take even more room.
I know the big titles look better in screenshots, they look more like published blog posts, which we like, but to actively use (switching between notes) the huge emphasis on the h1s (which are the least important part of my note) feels like the wrong focus
