I have an idea to create my own CellModel_Constant extension (i.e. concept that extends CellModel_Constant) to override something in behavior, constraint, and editor aspects. The reason for that is: I don't want to override generator aspects, I just want to add some Hooks. But I can't do it because when I use my own concept as a cell I always get a generation issue (something about "out of scope").
I would like to ask: what should I do (in principle) to just create a CellModel_Constant extension with, for example, just a minor change in the original editor? Which steps should I do, which aspect should I define, what kind of settings and where should I change?
Thank you in advance.
