That's what I love about Java (compared to Object Pascal and C/C++) - no
header required. Makes the code so much simpler, and I can drag and drop
to reorder methods as needed.

Anyway, I think Lazarus IDE can automatically declare methods for you in
the interface section - I think.

Overall, it's your preference. At least the good thing is, your are
breaking up large bodies of code into smaller chuncks. That's a good thing.

Alternatively, I'll create a class that does all the work I need. That
also makes it easier to unit test.

I know for a fact the Procedure List functionality (Ctrl+G) does support
nested methods.
