[eb3frn]

Hide the channel/inspector that not is in use. Only be visible when you make click on the spectrum during N seconds when will use in some module, and passt the N seconds will be hidden again.

In the Continuum RMS/Power meter, the yellow baseline can be moved using the shift key, as is possible to move the blue upper signal with control

In the Continuum RMS/Power meter disable the delta time and only will be active using pressing some key, maybe alt?

In the drift tool, the three leeds be in green color.

In the "SNR tool", replace the "Reset all name" for "Disable2 in the button.

In the remote tcp api, get the freq and amplitude of the current peak (bin with more amplitude of the FFT)

In the remote tcp api, get the current RMS of the 1st RMS opened inspector.

Put the color inspector tags in the waterfall area to have the upper spectrum clean.

The eSNNR value be a global variable to get from the infotextbox and also from the remote tcp api,

Thanks!
