MGLTilePyramidOfflineRegion should have a countOfTiles method that returns the number of tiles included in the tile pyramid. The implementation would rely on the mbgl::util::tileCount() function added in #9906.

Для моего разрешения экрана автомобиля и его физического размера, по умолчанию открывается слишком крупный масштаб карты. Удобный масштаб получается если 2 раза нажать минусик в масштабировании.
Можно ли добавить опцию заданного масштаба для запуска? Некий ползунок который можно выставить на нужный стартовый масштаб -20 -10 0 +10 +20

I think it'd be great to be able to move a Task between Projects, likely from the Task's Edit page.

This can help with keeping things organized, as you may not realize you'll need/want new Projects immediately, and it will save you having to either to export/import, or re-upload data (if you've not processed it).

For instance, I'd now like to move my Pix4D example datasets out from the Githu
