Steps to reproduce:

Minimal reproduction project:

applicable in any project.

I did a bit of digging around for this and the list order behaviour is as follows:

• Methods created before the previous reopening of the editor are in the script order
• All new methods are in the order they were created in, after the old methods

I understand that this would cause inconsistencies.
I could easily sort alphabetically the method list, so that it stays constant through reopenings of the editor. Same could be done for the base classes. Any objections?

If we can't mirror what source file order is alphabetical ordering is better than random order we have now. However ideally it would make more sense to try to mirror what source file order is people put functions in logical places for them.

[Sl3dge78]

The method list is updated at compile time and only the changes get added with every compile (which explains the behaviour)
Using the source file's order would require compiling the whole script with every change or add some complex sorting through the parser which I wouldn't be confident enough doing.
Alphabetical makes more sense to me and my major use case is to use the search box so it's doesn't matter much imo.

Confirmed reproducible in the current master branch.
