Hi Slawek,

Thanks very much for the feedback.

I should be able to do something here.  At present it's somewhat of an
experiment.

Not sure.  I don't think transparency is desirable for the OSM and
Sectional tiles,
as they are very dense information-wise.  However it would be worth
having for the OpenAIP

Yes :).  I've been struggling with this for a couple of evenings and
have yet to have it working
properly.

Yes. I'm 99% sure it would be possible to add these layers trivially
as new layers.

I think to do this we'd need to re-implement the window as a Canvas window.
That's fairly straightforward, but not something I'm concentrating on right now.
I want to build a set of layers for a G1000 implementation - the canvas map UI
is really just a way to display it.

I'll take a look at this.

That would be great!

Implementing the terrain maps you list above would be a very easy first task.
Plus if you're interested in improving the GUI, that would also be very welcome.
That's slightly more complicated, but there are lots of resources available in
the wiki and on the forum.

Best regards,
