Yes, you'll have to register.

done :)

Yes, you're right that the stepper (and other parts of the system as well) has problems with the 'x' flag - I wasn't aware of that. I'll try to fix this ASAP.

The 'g' flag doesn't make sense in the stepper, though. It is only meaningful for replacement operations - see the documentation.

Well, I don't know, in a way it would be easier to debug if the stepper continued on past the first match (with 'g' turned on) - ie. effectively simulating the 'replacer' and not the 'matcher', since otherwise I find myself going back'n'forth to select a new string start location.

Perhaps have a button (once the match has been completed) to restart matching at the location were the previous match finished? [ie. something like a pseudo-temporary invisible change of the string beginning]
