I'm not a coder, so I'm not going to pretend that this solution is easy to implement (it might be, but I wouldn't assume so), but how about allowing you to expose the "expert" options just temporarily (to find the tool you need) and then allow adding that to your new "novice plus" custom menus? I.e., if you use a menu option from the expert menu X number of times, it just shows up even though your default is the novice view.

Progressive disclosure? If you know your audience, you probably know what most people want, and then the usual next step up for that "one extra thing". You could start with the ultra-simple basic thing, then have an option to enable the "next step feature". If needed you could have progressive options up to the full version.

I don't know if this works well in general, but for example Kodi has "basic", "advanced" and several progressively more advanced steps in between for most of its menus. It hides lots of details that are irrelevant to the majority of users.
