[RFC] : Filter GUI

[Emmanuel <e allaud wanadoo fr>]

	Hi all,
I would like new ideas for the filters GUI, because right now it is not 
quite OK, to say the least. I was thinking in splitting it this way : one 
small dialog (unmodal) containing the list of all filters with 5 buttons : 
new, delete, edit + OK/Cancel.
Pushing edit button launches a new dialog, bigger that contains :
	- a text entry with the filter name;
	- a 2-pages notebook as now : one for action, one for conditions 
that make up the filter :
		* the action page just contains the same fields as now; 
but the mailbox selection will use the new widget or whatever Peter is 
doing now, to let the user have a standard way to choose mailboxes (thanks 
Peter);
		* the conditions pages : at the top a list of all 
conditions (just their type) and a radio button group to specify operator 
to apply between conditions (OR/AND). The bottom part will display the 
details of the selected condition depending on its type in text fields or 
whatever suitable. The you change in place what you want and push the 
apply button to validate the changes (or revert to cancel the current 
changes).

Comments, ideas are more than welcome because I'm really a poor gui 
designer.
Bye
Manu
