The Meaning of Life, the Universe, and Everything.
I remember black skies, the lighting all around me using AMIDST for finding places to set up colonies (and strongholds), and now that MCPE has gone infinite (Far Lands notwithstanding) I want to do it all again. Is there any tool like that? My world so far consists of an endless desert to the Southwest, an endless jungle to the East, Southeast, Northeast (there's a Extreme Hills like 3000 blocks to the North East tho, but I ain't making my world so big) and North, and an endless Mesa to the (North)West. No setting up colonies in fancy biomes is boring me (if we even had Desert or Jungle Temples at least, to build a village around them... I might make my own temple one day though).
Hey guys, just thought I'd post this here for anyone looking in the future -
There are two tools that I know of that are compatible with MC: Pocket Edition and Windows 10 Edition. There are MCPE Viz, which will map all of your explored chunks for you can can be used to find things like specific blocks, spawners, villages, etc. You can get it from it's creator's (Plethora777) Github: https://github.com/Plethora777/mcpe_viz
I believe there is also a way to convert between Pocket Edition and PC world versions using MCEdit, so you may also be able to convert your world to PC version and then use any compatible PC tools to accomplish what you want to do.
As Blocktopograph shows only the already explored areas,
I think it would be useful to make a mod, that would automatically travel over chunks,
for example over area: from (-1024,-1024) to (1024,1024),
to have all them "explored"
