ChangeLog:
v0.8a
-- Reintroduced the "Live" mode (thanks to
WiMo project), where continuous capturing is performed (low resolution only, thanks to HTC...
)
-- Experimental Autofocus tweak! Manually triggering the autofocus capability so to make the "Live" mode usable. Warning: not all devices/roms will be compatible!
