you can control the focus and LEDs from the touchscreen ,
or use the keyboard toggle button.

heres how you use the widget:
open the camera cover
then access the lfocus dialog by holding on the proximity sensor for two seconds

or

tap the screen once
tap on the indicator bar
tap the lfocus logo

you can either scroll left and right to set focus or just press on the right side or the left side to get a smoother focus effect.
you can also adjust the leds by tapping the go down button next to the focus bar.
you can add a timer to take photos/videos by clicking the clock icon.

by tapping the go down button one more time you will access the new toggle buttons which will have the following functions:

[Rem.LED]
(remember led state when capturing) (use only when taking videos)
[Stop RLED]
(auto turn off red led when capturing) (use only when taking videos)
[Timer.RLED]
(timer red led blinking)


for the keyboard toggle button:
a green indicator means the keyboard control is off
a red indicator means the keyboard control is on and you should turn it off once you're done.
turning on the keyboard enables focus via zoom buttons automatically and turns off the autofocus ability!
as for the keyboard shortcuts:

q-w led on/off
e-r recording red light on/off
a-s change focus
d fixes the sudden focus that happens sometimes after pressing the camera button,so press d first then adjust the focus with a and s so you don't get a different focus than the one you got with the camera button.
