Is anyone working on an enhanced Layer List that would allow grouping of layers? I'm still stuck using ArcGIS Online which restricts the size of tilepacks I can upload to ~2GB. This forces me to chop orthophoto mosaics into 20+ pieces for some projects to get them the entire mosaic online. It would be nice to have these all grouped into one layer for the end user to reduce the clutter in the Layer List.
