Obsidian has a plugin to handle typewriter functionality. However it's done, please please make typewriter scroll available! I never even realized how much it was needed until I started using NotePlan for note taking and it wasn't there. Just keeping the active line in the center of the screen relieves a lot of ergonomic stress. Focus (or just a quick button to toggle all sidebars closed) would also be nice, but typewriter scroll is really essential.
