you can use these constants inside the script.

I know, maybe I'll do that at some point, atm. I don't want to add another change.
First, the existing stuff needs to work.
Then I can look into things one at a time.
Atm. I spend an hour coding, just to see that you changed stuff and I can start rewriting again since there are changes everywhere.
Your RCs are basically alphas, normally RC implies a feature&interface freeze.
After a RC, there should only be bug fixes, no new features an interface changes.

=> until non-custom HAVC works, 'custom' stays removed.
Then I look at method 0, 1, 2, 4, 5, if the interface&co until custom works complete, custom gets disabled and I go back to first testing non-custom.
