Hi there - thank you for your feedback. The Network Map was always envisaged to give an overview of your network and to dynamically update when devices came online / offline. So it's more focussed on real-time information.
Reading your use case, as a power user, is very helpful. We will definitely look into adding an option to switch both the Network Map and Bandwidth Allocation into a table / list and providing more information on Bandwidth Allocation when there are several similarly named devices.
I appreciate that this doesn't resolve your usability issues right now, but user feedback is a big part of our roadmap so please let us know if you have any other feedback for us. This is just the first iteration of DumaOS and we have so many new features and improvements planned, which because the OS is fluid, we can do quickly.
