I have today tried to install many themes with the new khalpower v4.
Result was the follwing: I was able to get a decent outcome. Keyboard bug could be fixed but after a couple of theme flashes things started to get weired. First my gmail app stopped working.
After that I only got jibberish as fonts so that I was unable to change languages or anything else for that matter.
I'd very much appreciate ports for the new v4. Right now I'm using the fix described above. Thanks so much! Worked like a charm
