I'm posting here as I'm not a Facebook user but would like to comment on the enhancements posted on Facebook which I think look like a great addition.

For those that don't want this then a join type of 'none' could be added to disable the feature?

I would also like to see a wind vector added to the airfield brief window if possible (if an appropriate METAR or TAF is available at or nearby the airfield). There doesn't seem to be much space for this but I'm sure you could come up with a creative solution - how about a wind arrow (as in the wind instrument) superimposed on the runway graphic to show wind direction/strength relative to the runway direction?

Do you plan to have an Android Beta of this available - if so when?

The Standard Overhead Join in SkyDemon is the UK join. The link you gave doesn't actually link to a specific page, could you tell me where exactly you're looking please?
