First, I think the ordering of filters with break-out-points (Stop checkbox) is a powerful filter design, because you can keep single rules small and easy. Second, the need for understanding and using filter ordering and the stop checkbox partially comes from the fact that I cannot express a desired condition in one single filter only: (from startswith kris OR from startswith roth) AND (account is 'Private') filters mail to me on the Private account that is from Christian, who uses two different email addresses (either form work or at home). In the current filter architecture, this means having two filters: (1) from startswith kris account is Private [all conditions match] [stop filter evaluation] (2) from startswith roth account is Private [all conditions match] [stop filter evaluation] I'm not saying this is bad! It just adds to the number of filters I currently have in my list. For me, it is easier to keep track of the one, boolean filter above (named "Private mail from Christian") than the two lower ones, because it is congruent with natural language wording and thinking, but then I'm a programmer for a living. :-) Actually, I indeed think you are right in regarding a filter-redesign as lowest-priority item for PM at present, Jérôme. There are several features that should be addressed first which add much more benefit to users and as a consequence to CTM (which is also very important to me, PM being my second-most important software tool). Hereby withdrawing from further complex boolean filter discussion, Christian
