short intro:

Hi, I'm Moritz. I'm totally new to radio stuff, though I have some basic signal processing background. (more below :))

Is your feature request related to a problem?

When switching between analog and demodulated view in the interpretation. I constantly need to change the scale to see the relevant information

Describe the solution you'd like

the UI should stay as it is, but there should be two (or more) y-scale values saved in the background. one for each signal view mode. these should be loaded when the view is changed and saved when the scale is changed. (spectrogram could be constant, I/Q could be the same as analog, i guess?)

Describe alternatives you've considered

autoscaling as in #1003 might soothe the pain but i'm not sure its the best option

Additional context

Longer intro

Currently I'm trying to reverse engineer the protocol that my themostate (Vailant VR370f) is talking to the central heating. I'm super happy about URH, it has been a tremendous help (i tried grc and gqrx+audacity before). Anyway I'm currently stuck -- probably due to a) missing knowledge and b) shitty hardware: a 15€ RTL dongle
I will prob. open a couple issues. please excuse if some ideas are stupid :)
I also consider myself quite fluid in python, so I would totally like to help implement some features, if you like the ideas, and I would appreciate some guidance.
