The current MC PE world is too small(256 x 256). I think that this is just way too small. Since smartphones and tablets' specs have been improved, I think they could handle bigger worlds. If they couldn't, why not make a setting to toggle the world size and generation?
If you couldn't handle a bigger world(I doubt it with the new smartphone specs - nearly PC's from 4 years ago specs.), then you could nerf the settings. The size would be divided into 5 groups.
1. Tiny(160 x 160 - 10 x 10 chunks)
2. Small(256 x 256 - 16 x 16 chunks)
3. Medium(384 x 384 - 24 x 24 chunks)
4. Large(512 x 512 - 32 x 32 chunks)
5. Gigantic(768 x 768 - 48 x 48 chunks)
With the most up-to-date gadgets on the line, you could probably even use the 'Gigantic' option! If you can't, then toggle to smaller settings. If Minecraft PE is alreasy too bugged up, toggle to 'Tiny' to make the world 2.56 times smaller!

You know, this is actually a very good idea! I mean, just because some devices can't handle larger worlds doesn't mean the ones that can should be restricted. Well thought out my friend!
This is a very good idea, but, the problem is when giving others maps, there could be problems with the world size and the map... xD
Anyway, thats why i think it should just be stuck to 512*512, its not too big, not too small. Its just perfect, wouldnt create to much lag, as well as perfect size for when they add in caves.
Also, toggle-able height. You're still able to make big structures in MCPE, but they're not quite the same as awe-inspiring behemoths that can be made in PC Minecraft.
