New "looking Glass" app
Capable of showing a cascade with full bandwidth scan. You can select Min and Max Mhz for the cascade. You can move a marker so to (aproximately) know a particular frequency on the cascade. If you press the select button, the app will jump into the RX -> AUDIO app, already tuned into the just "marked" frequency. This first version SURELY has space for lots of optimizations and improvement in general.
