Huh, I never worried about re-allocating menu item arrays..
do you avoid it because it's slow, or is the idea to allow pointers to not change?

Reallocating unnecessarily fragments memory. find_item() walks the menu array every time. It's all absolutely irrelevant on a modern PC. I like that menus are not reallocated and my pointers stay valid. Especially under FLUID, which calculates widget addresses during initialization, this would be a concern. It does not really matter.

So, yes, find_item() every time is just as fine.
