The LG G3 D851 T-Mobile USA has an unlocked boot loader. Building CM for it only makes sense because LG has already mentioned they are working on a bootloader unlocking method for other variants. The D851's device tree would be the same as the D58X/F400/LS990 variants. This would advance the rollout of CM for most G3 variants, so they would have a more stable version once their bootloaders are unlocked.
You are not bringing new information to the devs, They will not work on it until there is a bootloader unlock for all/most models. Although maybe someone will start work unofficially for this model it won't get official status yet.
Yeah, I need this option to be there so I can enable the menu key. Currently, action launcher doesn't place the menu key there, so I have no access the settings and my Xperia Z has no hardware buttons lol.
It would be a nice feature if you could keep the navigation bar from going landscape and instead stay in portrait mode with only the icons rotating when landscape mode is activated. The Stock Xperia Z Soft Keys is a good example.
An also "nice to have" feature would be if the user could change the color of the background animation if a button is pressed. I don't like this light blue and would prefer white. But it is not necessary, just an idea.
