I love the way that nValt - https://brettterpstra.com/projects/nvalt/ - handles search.
There is only one box for typing - Search or Create. It not only searches the titles (like CMD+O in Obsidian), but also searches in files. The search results give precedence to matching files while still displaying results that only contain matches in files.
If your search DOES come back with a file name, pressing enter will open that file, otherwise it will create it (again, like CMD+O in Obsidian). Behavior is slightly different here, and, unlike Obsidian, you can create notes that are substrings of other notes (By pressing backspace after it auto-completes the name).
All of this combines to a reduced cognitive load when editing notes. If I’m watching a video about, say, MongoDB databases, I don’t have to know whether I already have existing notes about that topic, I just start typing “Mongo,” and if nothing comes up, I can press enter to create a new note. Seconds saved every time you open the app add up!
