// Color bitmaps generated with:
// Gimp image > indexed colors (16), then "xxd -i *.bmp"

// Note about available RAM:
// Check what ends up in the BSS section by looking at the map files !
// Use constexpr where possible or make sure const are in .cpp files, not headers !

// Note about messages:
// There can only be one message handler for one kind of message at once
// If an attempt is made to register a second handler, there's a chDbgPanic "MsgDblReg"

// Note about matched filters: see proc_sonde.hpp

//TEST: Goertzel tone detect
//TEST: Menuview refresh, seems to blink a lot
//TEST: Check AFSK transmit end, skips last bits ?
//TEST: Imperial in whipcalc

//BUG: Console lock-up if first string to be printed starts with escape character ?
//BUG: (Workaround ok) CPLD-related rx ok, tx bad, see portapack.cpp lines 214+ to disable CPLD overlay
//BUG: SCANNER Lock on frequency, if frequency jump, still locked on first one
//BUG: SCANNER Multiple slices
//GLITCH: The about view scroller sometimes misses lines because of a race condition between the display scrolling and drawing the line
//GLITCH: Start of tx using ReplayThread plays a small bit of previous transmission (content of 1 buffer ?)
//	See fifo.reset_in() ?

//FIXED: Update button in signal gen doesn't work for shape change
//BUG: Signal gen noise shape doesn't work
//TODO: Continue acars receiver. See matched filter, probably doesn't shift the spectrum correctly
//TODO: Add larger description text field in frequency load, under menuview
//TODO: Allow apps to select a preferred FREQMAN file
//TODO: Make play button larger in Replay
//TODO: Add default headphones volume setting in Audio settings
//TODO: Put LNA and VGA controls in Soundboard
//TODO: Make CTCSS display only when squelch is opened
//TODO: DCS decoder
//TODO: Increase resolution of audio FFT view ? Currently 48k/(256/2) (375Hz) because of the use of real values (half of FFT output)
//TODO: Move Touchtunes remote to Custom remote
//TODO: Use escapes \x1B to set colors in text, it works !
//TODO: Open files in File Manager
//TODO: Ask for filename after record
//TODO: Super simple text file viewer
//TODO: Clean up ReplayThread
//TODO: Cap Wav viewer position
//TODO: Adapt wav viewer position step
//TODO: Use unit_auto_scale
//TODO: Remove make_bistream from encoders.cpp, too complex, stinks. bitstream_append should be enough.
//TODO: Continue work on proc_afskrx_corr, see python script (it works !)
//TODO: De bruijn sequence scanner for encoders
//TODO: FILEMAN Move files
//TODO: Use separate thread for scanning in EPAR TX
//TODO: Make freqman refresh simpler (use previous black rectangle method)
//TODO: Merge AFSK and TONES procs ?
//TODO: NFM RX mode: nav.pop on squelch
//TODO: MORSE use prosigns
//TODO: MORSE live keying mode
//TODO: Use to_string_short_freq wherever possible
//TODO: SCANNER Waveform widget as FFT view ?
//TODO: Optimize (and group ?) CTCSS tone gen code
