I have been waiting patiently 3 months for LevelDB format support on PocketMine. I have not seen progress map support for LevelDB in the past couple of months. I know programming can be difficult so it can take a while. I am also aware that @shoghicp thought that 0.9.0 worlds were going to use Minecraft PC world formats so he implemented that, but Mojang used LevelDB, that is why PC maps are supported and not PE maps. I am just wondering when will LevelDB be implemented into PocketMine.
