Please add a Table of Contents filter for layers' scale visibility. Ideally as a user zooms in and out of the web map layers set at that visibility scale would show up in the TOC. This would improve the multiscale map building workflow.
Currently there is a "Visible" option (which I initially thought did this by the name and I was excited) but this only displays TOC items checked/vs unchecked.
Thank you for your consideration,
Amanda
