@Raid have you seen this work that S.V.I has done in enhancing the HTC EZInput Keyboard I have been using it before your kitchen and it makes the keyboard much faster at typing as well as reduced ram footprint(I know you'll like that).

I also found that I am unable to add my own SMS style tweak, is there anyway to remove the changes you made to the SMS threading look to revert it to defaults? Thanks for your great work and nightly kitchens.
