Thank you for investing your time into this explanation @steemchiller! While not a programmer on the Steem blockchain, I do have some programming experience, so this makes perfect sense.

"... and have it all in a base class. It's more effort to build it like this, but, as you said, it pays off in future."

I was going to execute a favorable (to you ...) transaction just now in SteemWorld and the Transfer tool appears to be gone!? I use this feature regularly, so ... Hate to have to go somewhere else, but not sure what else to do at the moment ...
