/* TODO
 * 22:22:17 <seanegan> deryni: speaking of notify.c... you know what else
 * might be a neat feature?
 * 22:22:30 <seanegan> Changing the window icon.
 * 22:23:25 <deryni> seanegan: To what?
 * 22:23:42 <seanegan> deryni: I dunno. Flash it between the regular icon and
 * blank or something.
 * 22:23:53 <deryni> Also I think purple might re-set that sort of frequently,
 * but I'd have to look.
 * 22:25:16 <seanegan> deryni: I keep my conversations in one workspace and am
 * frequently in an another, and the icon flashing in the pager would be a
 * neat visual clue.
 */

/*
 * From Etan, 2002:
 *  -Added config dialog
 *  -Added control over notification method
 *  -Added control over when to release notification
 *
 *  -Added option to get notification for chats also
 *  -Cleaned up code
 *  -Added option to notify on click as it's own option
 *   rather then as what happens when on focus isn't clicked
 *  -Added apply button to change the denotification methods for
 *   open conversation windows
 *  -Fixed apply to conversations, count now keeps count across applies
 *  -Fixed(?) memory leak, and in the process fixed some stupidities
 *  -Hit enter when done editing the title string entry box to save it
 *
 * Thanks to Carles Pina i Estany <carles@pinux.info>
 *   for count of new messages option
 *
 * From Brian, 20 July 2003:
 *  -Use new xml prefs
 *  -Better handling of notification states tracking
 *  -Better pref change handling
 *  -Fixed a possible memleak and possible crash (rare)
 *  -Use gtk_window_get_title() rather than gtkwin->title
 *  -Other random fixes and cleanups
 *
 * Etan again, 12 August 2003:
 *  -Better use of the new xml prefs
 *  -Removed all bitmask stuff
 *  -Even better pref change handling
 *  -Removed unnecessary functions
 *  -Reworking of notification/unnotification stuff
 *  -Header file include cleanup
 *  -General code cleanup
 *
 * Etan yet again, 04 April 2004:
 *  -Re-added Urgent option
 *  -Re-added unnotify on focus option (still needs work, as it will only
 *  react to focus-in events when the entry or history widgets are focused)
 *
 * Sean, 08 January, 2005:
 *  -Added Raise option, formally in Purple proper
