We could add a ping plotter/ping route R-App, it could be useful to see what parts of your packet's trip are causing lag. We could look into adding a third 'spectate' type to allow/deny enable watching server without impacting the rest of the geofilter, or adding another panel which hosts a list of servers that it pings. Thanks for the suggestion.
VLan is definitely a useful feature, we plan on adding it in a later version.
We are definitely interested in expanding the appeal that our routers have. Parental controls would be a nice addition to DumaOS, it could have features like periods of time devices can access the internet.
I'm not sure I understand what you mean by not supporting a Nintendo Switch, you can configure your Nintendo Switch devices in the device manager and the R1 allows full port forwarding from 1 - 65535 on both protocols. We don't currently have DMZ in our R1 firmware but we do plan to add it in a later version.
