* simplifications, better precision, less sleeps
* fixing glitches
* fixed res freeze
* correct frequency picking for marker, yay !
* added comments into the code in hard parts
* took out unneeded sleep
Special thanks to users vmakeev, tel, f1ghy, u-foka for their resilience in testing the bunch of bins I've produced to fix the thing :-)
* Use receiver/transmitter models everywhere
* Run formatter
* Fix a copy-paste bug, make transmitter_model actually set tx_gain.

Discord User jteich did some investigation (Thanks!) and helped me understanding this rather obscure parameter:
Internally, is called "TRIGGER", and is passed into the baseband when configuring the desired spectrum sample rate.
Please forgive me in advance if this explanation is not 100% correct. It's only my interpretation, based on my own observation and jteich's comments over Discord chat.
This trigger parameter apparently determines the amount of data over time used for calculating the signal's power inside each specttrum's bin, before considering it "done".
In short, if you lower this resolution value then the cascade will tend to be rendered a bit faster, while kind of blind to tiny signals.
On the other hand, a bigger value will help rendering and distinguishing different signals on the cascade.
Too big a value can easily clutter up the cascade. But then it may be a "blessing" when inspecting higher freuqencies -where hackrf is more deaf"
The default value of 32 is quite decent. But then, now you can experiment with it. Cheers
Added a PRESETS.TXT file (inside /LOOKINGGLASS folder).
Also optimized the way the spectrum signal is integrated into the cascade.
Added provision for ranges lower than 240MHz but I am afraid that at this time it will not be advisable to lower ranges any more than 240MHz, since some artifacts and frequency running - moving out of place- occurs.
I can only hope that someone with a better understanding of hackrf's inner code can fix this issue and perhaps enhance the scanning speed.
I found some "original commenting" inside the code:
// TODO: Move more low-level radio control stuff to M4. It'll enable tighter
// synchronization for things like wideband (sweeping) spectrum analysis, and
// protocols that need quick RX/TX turn-around.
Which makes me think that there are things "missing" from the portapack side of the code, for allowing serious speed sweeping. So I am concluding that with current "portapack framework" this might be "the best possible thing".
It is to be noted that the "new" internal sweep mode code is signed by:

Maybe Mike or Dominic can be contacted and hopefully lend a hand on enhancing this code.
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.
