it would be Wrong™ in my opinion to put such things as screenshots in the repository (since doing so permanently increases the total size and it's more like a build product than a source file)
(I keep not wanting to because I see all the not-really-finished things in the UI.)
I don't get all these complaints about no demos/screenshots. It's like people don't want to spend 8 hours screwing with GNU Radio, gr-osmosdr and the obsolete version of Python required to run them, tracking down a driver for hardware that they may not actually own, setting up the hardware itself, and then making all this stuff work on a server that may or may not actually exist at the moment.
Personally, I blame today's culture of instant gratification.
A public demo instance is blocked on adding sufficient anti-DoS provisions to the server. One possibility I've considered is to make a simulation-only version packaged for Sandstorm, which would allow for a one-click trial experience — but not show any actual RF, so the internal simulator would need to be made much richer to actually show off the features.
