> you have to design to a lowest-common-denominator that balances
Something that's always stuck with me is a bit from the book "Don't Make Me Think" about cost vs. value in attention and complexity, that when you add a feature used by only a small percentage of users you're "taxing" 100% of users for the benefit of a few. That you should optimize for the common path and not edge cases. Over two decades later I still find this an exceedingly difficult challenge to juggle that doesn't just mean hiding advanced features behind extra menus.
Menus, gestures, keyboard shortcuts, advanced versions of the interface locked behind preferences, and fully customizable menus (including user-defined macro buttons). There are a ton of ways to hide the complexity for common users without frustrating power users. The challenge for the designer is the taste/judgement to know which features to show/hide and where (as well as how to organize all the menus logically).
