Is there any themes for the Reuleaux RX75? Like there is for the RX200 and 200s? I did a firmware update with my RX200 to change the appearance of the menu, text, etc. Is there any way to do that with the RX75? The RX200s and RX75 see to have similar screens/layouts. Would it be possible to do a theme update made for an RX200s and flash it to an RX75? Really interested to know this. Chime in if anybody can give me some insight.
