Tx for responding.
My feedback isn't specific to Rows. The dealbreaker for us was post-evaluation. On paper, the alternative option looked preferable but it wasn't until we started using it that the friction became problematic.
The only suggestion I have is to closely watch standard interactions that users coming from a traditional spreadsheet have.
Rows looks great and I hope my post didn't come off wrong. The issues I had may (or may not) be applicable to Rows. I appreciate your willingness to listen.
