The other problem with OzRunways and AvPlan traffic is, unless it's from an ADS-B output (and even
then there's a lot of erroneous callsigns, particularly among the RAAus/HGFA crowd), the callsigns often bear no relationship to reality. So even
if you identify them as a potential conflict, how do you call them?
"Brisbane Center, Alpha Bravo Charlie, are you talking to Crunchie who's doing airwork south of Dalby?" 
Here's a snippet from SEQld right now. Crunchie and Arch are out and about, someone with no callsign (
Unknown) is tooling around Caboolture and there's a Dash-8 in the mix too.
So how do you address Crunchie or Arch? Are they in a Drifter or a Diamond? Doing circuits or airwork in the area or a low-level NavEx? Neither have got an active flightplan in the app so you don't know what their lateral track is going to be nor can you infer they're on a cross-country so will be climbing to altitude and staying high. At least the Dash-8 Driver has
his plan showing so you know where he's going and that he might be an issueif you're also going to Chinchilla.
