Base Structure Dialogue Should Be Minimized by Default #4268
Description
The base structures dialogue is awesome, but really complicated. It's extremely confusing for beginners, and likely used less than the rest of the Create Structure dialogue. Additionally, since "Structure size" is labeled as optional, it makes it feel like the rest of the fields aren't and that there is something else you should be interacting with before creating your structure.
For all those reasons, I think that the base structures portion of that window should be hidden by default, and probably remember the last state the user had it in (so if people are using it a whole bunch, they can continue to).
Lastly, we should probably add a (?) button (that links to the docs) or just add more words to "base structures" since it's not entirely clear what it is if you're not thinking about OOP/inheritance/classes/etc.
