Implement "queue stall" function to reset waterfall to default settings if the CPU does not keep up.

Logging:
- save to log
- search in log, show log, modify
- import/export ADIF

Channels:
- uppercase/lowercase only, dependent on modes?
- status line (other call, mode, RX/TX state, frequency

Macros:
- selection of all plausible macros on macro editation
- import/export files with all macros

Documentation
- online on PocketPC
- web update

Configuration:
- soundcard RX/TX selection (for bluetooth or USB sound card)

Waterfall (low priority)
- window selection (hamming, triangle ...)
- Compute FFT just of a part that is displayed (Zoom FFT). That shall save a lot of CPU cycles
	Update: 2007/12/22: It is already heavily optimized and will not save much.
		Most time is spent on screen refresh, scrolling of RX window.

- turn receive off when the application is not active (switchable)
- reset suspend timer (switchable, longer suspend timer)

Modes:
HELL - write the papertape widget
OLIVIA - check squelch values
RTTY - add AFC, squelch

deregister old notifications if the program was not exited correctly

look at Domino improvements in fldigi

Channel equalization or equalization for input filter 
Configure printing of unprintable characters (special characters, >128 etc)
Add Navtex/Sitor.
