P.S. Little annoying problem - it works bad with adding big layers(30k tiles) - it copying it and then nothing, but after restart this layer appears, but without zoom levels. and after merging it breaks on calculating zoom levels. So option for recalculation will be very helpfull.
P.P.S. Also option to merge session layers will be very helpfull.
In a file system the zoom levels folder is empty too?
Yes, it is possible to add function for mannual recalculation zoom levels.
