Create A beecon
updates @click
upsize B via dbus if necessary
switch on B via dbus methods on paramater widgetVisible and update_content post-action
DBUS reset_rearm_timer (several seconds) in B for auto-hide
DBUS force B to update_content

Create B beecon
create landscape png image with applications grid (BL)
setup Exit Status = 0 image to BL
setup Exit Status = 1 image to BP
updates @click
create portrait png image with applications grid (BP)
calculate coordinates/sizes for hotspot grid both for BL and BP

if timer execution then downsize B via dbus if necessary, switch-off and hide, disarm timer
if DBUS execution then fetch device orientation:

read 1st value from /sys/class/i2c-adapter/i2c-3/3-001d/coord
if 1st value between -700 and -1000 then orientation is P
if 1st value between 0 and -700 then orientation is L
store position in B via echo (P or L) or rememberme placeholder;
exit 0 to display BL or 1 to display BP according to sensor

if CLICK on B then retreive hotspot according to orientation and run relevant application
