Added a nicer MARKER (thanks to XSX(H1) contributor for the suggestion)
Fixed a bug that made the screen scroll from top, when using a popup "window" and returning (like, when pressing the DC VOLTAGE enable / disable" button on top bar) THanks to GregoryFenton for the testing and bug spotting!
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.
