I have been using Skydemon for IFR flights for a few weeks now.
It would be helpful if I could select just one STAR, approach and one SID (chart + SID text) and have a button on the right side of the screen (like for notams, weather, radio and airports) were I can slide the chart into view.
Consider an IFR training flight A-B-C. At airport B we start with a STAR or RNAV transition, fly the approach and use a SID for departure.
Most approach charts are geo-referenced. Most SIDs and STARs aren't.
So, I can see the approach easily, but if I need to review the transition or SID, I have to open the PDF file from the airports tab.
It is feasible to switch apps in Android, but Skydemon on my device opens the PDF file in the external viewer BUT I can not switch back to Skydemon without closing the PDF again.
During climbout I have to be heads down to open the airports tab, (sometimes with the wrong airport open by default) select "Instrument Plates", dig through the list (check EDWE - the Y and Z approaches are mixed up) and select the proper SID. Probably not the smartest thing to do at low altitude.
If I could populate buttons for STAR, Approach and SID I could just quickly switch back and forth as required - especially if the charts would open directly in Skydemon without third party apps.
