/* TODO:
* - the dialog box could be non modal
* - in that case,
* + could refresh channels from time to time
* + set the name of exec (and perhaps its pid) in dialog title
* - get a better UI (replace the 'x' by real tick boxes in list view)
* - enhance visual feedback: the list is large, and it's hard to get the
* right line when clicking on rightmost column (trace for example)
* - get rid of printfs (error reporting) and use real message boxes
* - include the column width settings in the full column management scheme
* - use more global settings (like having a temporary on/off
* setting for a fixme:s or err:s
