 TODO
 =====================================================================
 
-- Selections
-- More optimisations
+Adding many lines makes it terribly slow.
+
+Printing produces empty pages only.
+
+Formatting of first text in message in M is broken.
+Large images in last line don't get displayed properly.
+Taking last line's height as default for next is rubbish,
+use "default height" and adjust as necessary.
+
+Selections:
+  - moving in negative direction doesn't work
+  - selection state not properly reset, only works once
+  - selecting non-text objects is strange
+
+wxllist::GetSize() requires extra Layout() call, which should not be
+necessary. Find out why this is so.
+YES, it is necessary, because the normal drawing only happens within
+the visible window.
+I must find a way to re-Layout() objects. This is only required after
+their sizes change:
+- Just mark them as dirty:
+    - mark current line as dirty when editing it (so width gets recalculated)
+    - mark all following lines as dirty when changing font settings
+    - Let Layout() work only on the dirty lines.
+  !!! GOOD: this can also be used to recalculate the wxLayoutObjectCmds'
+            fonts! :-)
+
+- searching for text
+- moving cursor in non-edit mode
+- cursor screen positioning ignores font sizes once again :-(
+   --> UpdateCursorScreenPos() cannot work as it ignores previous font formatting commands.
+       Either draw cursor when drawing text, or wait for new wxLayoutObjectCmd to be fully
+       implemented.
+
+RECENTLY FIXED (?)
+  - fix(simplify) cursor size calculation
+  - delete in empty line doesn't work
+  - fix horiz scrollbar size OK here, a Mahogany problem?
+  - with a large number of lines, wraps to top of scrolled window
+    --> check where the problem lies, add a debug function showing all coordinates
+  
+- update rectangle (needs support in wxllist and wxWindows)
+  --> needs a bit of fixing still
+      some code bits are commented out in wxlwindow.cpp
+      offset handling seems a bit dodgy, white shadow to top/left of cursor
+
+
+  - replacement of llist in window
+  - undo
+  - font optimisations(!)
+  - occasionally wraps lines wongly (twice) ??
+  - UNDO
+  later:
+    - DragNDrop ... broken in wxGTK at present
+    - cut&paste ... broken in wxGTK at present, Paste already implemented
+    - Selections
 
+- More optimisations:
+  - let each line have a pointer to the last layoutcommand and let that
+    one only store the settings that changed, then we no longer need to
+    recalculate all the lines
