 *** Current status of THREADS implementation ***
 
-
-CHANGES IN RELATION TO ORIGINAL PATCH
-    - don't add nested messages into selection on collapse if parent message
-      is in selection
-    - some changes in messages highlighting
-    - re-written all changes in rcube_imap.php
-    - temporary removed threads caching (see TODO)
-    - use depth=0 for roots
-    - thread expand state is not stored anywhere
-    - removed imap_thread_algorithm option, we're using the best algorithm
-      supported by server and implement REFS sorting in Roundcube
-    - use underlined subject for root with unread children (icon is still supported)
-    - on deleting messages the whole list isn't refreshed
-    - added 'expand unread' button
-
 TODO (must have):
     - threads caching
-    - updating threaded message list on message delete
-    - don't reload messages list on check_recent
-
-KNOWN ISSUES:
-    - on new message (check_recent) the whole list is reloaded
-    - css issues on IE6
+    - (better) updating threaded message list on message delete and check-recent
 
 TODO (other):
-    - performance: fetching all messages for list in "expand all" state only,
-      if "expand all" is disabled we should fetch only root messages and fetch
-      children on-demand (on expand button click),
-      Notice: this is not so simple, because we need to fetch children
-    	      to set "unread_children", but we can fetch only flags instead of
-    	      all headers for each child
     - button in #listcontrols to mark all messages in current thread (with selected
       root or child message),
     - icons for thread tree structure
 
-TODO (by the way):
-    - use jQuery.inArray instead of find_in_array() (common.js)
+KNOWN ISSUES:
+    - IE6: message, flag, attachment icons are not displayed in 
+      initially collapsed child rows
