Make that two customers who would love a night vision toggle of Plan-G. Getting the default OpenStreetMap to go dark may be the real issue.
Maybe payware 3rd party maps have an option. Still if possible it would raise the bar making Plan-G the "must have" moving map for X-plane
night operations. There will be a dozen YouTube videos showing it off! :)

Here are XP-11/Plan-G_3.2.0.144 two monitor examples. The night version is just a negative image created in a photo editor for effect.

Greetings,

I've been running Plan-G for free a month and decided to donate as I think is it definitely worth 20 pounds sterling! Tim has put a lot of work into this including updates for X-Plane 10.22 64 bit which makes our flying chores a lot easier. Actually if I was Tim I would charge for Plan-G!

Before Plan-G I was using X-Mapper Pro on an iPad to see where I was in the world and XPFlight Planner to easily create flight plans then load them into a FMC on my aircraft. I still use the planner but love all the info Plan-G gives me while I'm flying there.

One problem is night flying where X-Plane is on the left monitor and Plan-G on the right. Plan-G is so bright I can't see the night details on X-Plane on the left. So I minimize it then bring it up once in awhile to check my status.

Thus one solution is to port the program over the Apple store to run on iPads with a WiFi connection from the PC. Then the iPad does not interfere with the main monitors and all is well. All should work as the iPad keyboard works OK as well as after market Taurus keyboards which work great. I'm not a text guy but with the Taurus I can send three pages to a cell phone and drive them nuts! I love it!

Apple just updated their IOS to 7.02 and X-Mapper Pro won't currently work with it. Thus Plan-G has an opportunity to sell thousands on the Apple store for say $5.99 USD!

Let's help Tim get to an iPad version so he can buy a Ferrari!

Best Regards,
George
