Hi - forgive me if this has been suggested it just popped into my head and figured I'd post before I forgot about it.
It'd be handy to be able to overlay the mesh/topology maps atop a floor layout image that I upload. It's cool how you can move the nodes around, to rearrange, but the ability to save their positions (relative to a background images absolute pixel origin (0,0)) doesn't seem like a stretch?
I guess one challenge would be multi-level/other stories... Maybe (as a later revision) you could assign "visibility" to nodes and multiple overlayed images (would require transparent support) to view all or only one floor at a time?
Also, nodes which are "mobile" or not fixed position. But, I personally don't use zb/zw for devices that don't stay put, as matter of policy.
Just spitballing.
Thanks for the consideration!
