Thanks for this great tool!
Everything works great, Selecting Areas, Zoom Levels, downloading, Stitching, creating files for geoconvert.
Only weak point in the moment is geoconvert. I had to increase swap space significantly to avoid geoconvert system crashes on windows 10. Geconvert needs up to 25 GB when converting. Next point is I have to convert in smaller partitions. When aeroscenery starts too much instances of geoconvert, everything gets unstable and often stops working.
I think when geoconvert can be started once, writes some protocol and ends itself with a defined exit code and can then be run with the next area and so on, that would be a wonderful workflow.
