Since this topic appeared on several discussions I had a check for my own mission profile. First, I did not recognize a change as I am using Skydemon2 for German airspace, never liked the harsh (Gerrrmann? little and hard colors in that style sheet) DFS-stylish display.
Yes, I agree with fellow pilots that the current DFS-ish display of E is not the best.
Yes, as an IFR traveller using Skydemon for VFR parts, I totally agree with Skydemon to NOT let airspace E be switched off.
I can imagine the personal view of VFR-only, restricted microlight and ultralight pilots to ask for it, but folks - you are not alone in the sky!
The always visible boundary between controlled and uncontrolled airspace is a sure safety benefit for all of us, in my opinion.
A Proposal: Change the color of airspace E boundaries to the greenish as in the Skydemon styles could be a compromise.
