First of all, thanks for the fantastic app! I use it very often!
Because most of the times I zoom and move the map in approximately the same area back and forth (e.g. one small part of a city where I reside), would it be possible to integrate an option to background calculate a larger ‘out of screen’ pre-rendered area and a pre-render for different zoom levels for that area? When I zoom out on one area and successively zoom in on that same area, it has to re-render everything. Or when I move to another nearby part it has to render that part. While it already could have been pre-rendered on the background while I was looking to the map. This would greatly increase the perceived speed of the app. Especially in the Netherlands, where some parts take up to 5 seconds of rendering times on my 4S.
Probably continuously pre-rendering in the background of tiles will decrease battery life, but for me an option to do so would be most welcome! (But I do not know if it is in any way technically possible).
Furthermore, I miss the soft fade-in tile option from the previous version… (but maybe I am the only one missing that option).
Keep up the good work!
