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