Sorry for my english. So WiUi 4.3.14 use stock radio, I didn't change it.
Did you tried the latest WiUi?
1. Busybox already in
2.Why? In my opinion CWM 6.0.3.2
(13-11-15) working very well.
Anyway I like up-to-date ROM, but the latest CWM break some scripts as I said before, I will try to fix it.
3. I didn't remove Weather app, but you can remove with Aroma
4. I thinking about it, couple week ago, but I don't want to increase ROM size too much.
I like Stock Camera app. If anybody need it, he/she can flash it.
If Miui v6 will be arrive, of course I will add some extra Camera from other KK Roms.
