When I'm using the planning tool during the design phase, I found that I miss the ability to be able to hide an AP temporarily in order to A/B cell coverage with it on or off. I have to remove it completely and that disrupts my initial placement. A lot of times I end up having to clone the map to be able to quickly A/B predicted models.
Another way to think about this is to possibly add a Radio On/Off toggle, which would be useful in certain high-density deployments where 2.4 GHz radios may be turned off. Being able to semi-accurately model that propagation would be a convenient feature to have.Not only that, but I think a feature that compares two APs' cells would be helpful, sort of like the ACSP neighbor function. For example, if I want to attempt to model roaming thresholds between three APs and fine tune placement, examining each of the three cells individually in groups of two may be more helpful than all or nothing.
