IME, "intuitively obvious" is a red herring for any halfway interesting interface. This was best captured by a coworker of mine decades ago about a feature: "It does what you expect, but you have to expect the right things."
What I strive for in an interface is consistency (both internal and with existing conventions) which maximize the chances that someone will already have learned the relevant interface conventions (or trained their intuitions, if you like).
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
