Is cool ............ (Thx seria )
But please note that any such gadget's - memory load, which in devices such as HD and FullHD screen is not insignificant!
IMHO - it is better to have a smoothly operating navi, than navi with EXTRAS - but the "jamming" itself.
Note: This applies to all add-ons and additional tools !!! - Which are loaded during the run.
If the user has a device that has more than 2GB of memory - it's no problem .... otherwise the effect may not be smooth ..
