All I needed to see to know this is worth my time investigating is here:

Customer testimonials

"All in all an excellent offering. I really like it, and I think it could be quite useful to Zen Cart vendors." – Scott Wilson, That Software Guy


"I am very impressed with ShopAdmin. As a developer, I wish it came with Zen Cart because it would make my job so much easier! Comparing it to Easypopulate? No contest, this wins hands down. I will be glad to recommend it to customers."
— Delia Lunsford, Web Consultant, Delia Wilson Design
That plus the constructive comments (vague unsupported comments do not help the community) I've seen posted in this thread are good enough for me to investigate and test this app out for myself.. I only have one question for the community:
Is any one using this with one of the working SEO mods (Ceon's URI or SSU)
