Hello all! This is my first suggestion, and I would like to propose that Mojang add support for keyboard and mouses in MCPE under Android. There are numerous Android devices that feature keyboards and touchpads/mice built in, such as the ASUS Transformer series (shown above). Others include the MyTouch 4G, HTC Evo, Motorola Droid 4, and countless more 'mini-pc' Android devices with no touchscreen.
Giving keyboard and mouse support should be fairly easy to accomplish, since it has been done in Minecraft: Pi Edition (that shares code with Pocket Edition). This feature would allow owners of Android devices with physical keyboards to play Minecraft exactly like the PC Edition, with WSAD controls.
This could also be extended to the Apple Keyboard on the iPhone/iPad platform, but I have no knowledge of that since I do not own an iPad/iPhone. I believe Apple also disallows iOS from using Bluetooth mice, so that could limit functionality on the Apple platform. Let me know what you think!
It's also possible to have keyboard and mouse support if your tablet has at least 1 USB port and if you have something that extends the number of ports. It's pretty handy, and now I feel like not playing Minecraft PE ever since I did this. I fully support this idea.
