There is a plugin that displays the current note as the window title in the top Obsidian title bar. Called something like Active title to window title or something like that.
There’s also the Andy Mode plugin that allows you to toggle vertical note titles as Andy’s website does when viewed through a desktop browser. (its really slick, take a look)
Note that wording titles positively is a very underrated tip. Doing it allows you to chain notes together in outlines to form a readable series of instructions, principles, etc.
Not every note warrants this of course, some are topic-based or otherwise capture a concept or process rather than a specific principle.
But if you try to do this more often than not then it is a very powerful protip.
