I think I responded to all your comments. I wasn't sure if I should remove the define split commands. Everything seems to be working at the moment.

We probably gonna deprecate define in favor of follow. No sense adding another define then.

[jaresty]

I'll remove the define changes then, when I have some time. If you want to make changes here before I get to it please feel free (I'm away for the week)

[jaresty]

I removed the define command. Only the follow command remains.

[jaresty]

I think I addressed all the comments. Anything I missed?

Thanks for cleaning it up! @pokey

Nice exactly what I wanted! :)

I didn't actually read any of your comments, so it's a good sign that we independently arrived at the same conclusion 😄

Heh don't know if I should be hurt or impressed by that :D

well they had all been marked as resolved so I assumed they'd already been addressed 😅

Oops, sorry. I was using them kind of like a todo list-should I have left them open? Appreciate all the guidance-thanks for helping me get this done 😀

That's ok. If you're confident you've resolved them, feel free to mark them resolved. If you have any doubt, though, best to leave them open and let us have a look to see if they've been resolved
