I modded the black keyboard theme out of AeonFlex for a more simple look, and did a second version with softer corners by request.They should work with any rom using the LG Keyboard (including G3 keyboard!) but please let me know if they don't. Just download & install like a normal apk. (attached)
The apks have been zipaligned.
Here is the LG Keyboard app if your rom does not include it.
°YMMV with installing & I can't provide much support...
