Good work so far. This one is still a little rough around the edges. Besides the suggestions, take a look at my comments about some structuring modifications.

I made the suggestions to one version, so please also cross-apply them.

Also great work - accept the suggestions and cross-apply them to the other version, and this PR is good to merge!
