-)	Improve the handling of the folder tree. Only display the first level. 
	Clicking dbl-left opens the folder, Clicking right should open and 
	place an extra list with the subfolders. Clicking right in the left 
	most window should delete those lists again, and open the next 
	appropriate one. This could get messy if there is a very deep nesting
	maybe just create one sublevel list, and redisplay this list when the 
	user wants to go a level deeper. Also find a way to make menus that 
	depend on the folderlist cascading in stead of just displaying them all.
	It's ok when you don't have too many folders, but not if there are a 
	hundred of so...
	
-)	Implement the pick mechanism (in development)

-)	Add key bindings to a lot of the windows.

-)	Add some checking on list lengths to adapt the sizes of listboxes
	between a min and a max value

-)	Add some processing for backed up files

-)	after updating the alias list, only the "Mail To" menu in the
	control window is changed. Also change them in the folder and show
	windows... Handling it the way I do the MH configuration (by deleting
	all windows, which is good there) isn't ok here. Maybe find all
	windows, and then update the buttons in them. must be possible..

-)	Add a check for editing after sending. Ask for confirmation on 
	forgetting changes. Also improve the editor. Add the possibility to
	include the message that is being replied or forwarded to...

-)	TkMH only handles folders in the Mail directory. I don't think I'll 
	change anything about that behaviour.

-)	make it the users choice which commands he wants to use for
	scanformat, and the commands forw, repl and show.

-)	Make it possible to use a different editor if there are a lot of 
	complaints about this one...

-)	Find a good way to toggle the checkbuttons in the edit and display
	and folder windows, without affecting the others. using a different
	variable name for each window doesn't seem to work very well.

-)	When creating a .mh_profile, try to do it intelligent, by filling in
	a default for the .signature and the Maildrop.

-)	Group the procedures in the lib files in a little better way, so they
	won't be loaded when nor necessary

-) 	make it possible to copy a message to a file... maybe stripping 
	the header

-)	More bitmaps for icons? Scan the PD bitmap libraries...
