Description of Problem:  When adding several criteria to a filter, you have
to manually scroll down the list for each additional criterion added.  This
is not user friendly (especially considering the default window size has
room for just two criterion without scrolling).


Steps to reproduce the problem:
1. Add 20 criteria to a filter (I commonly do this for my spam filter)


Actual Results:  Each time you click Add, you have to scroll to the bottom
of the criteria list then click the appropriate field.  If you use the
cursor keys, you can move from criterion to criterion, but the scrollbar
does not move to keep the current selection visible.


Expected Results:  When adding an additional criterion, the criteria field
should automatically scroll to the new criterion and give focus to the
first drop down list box.  Make the gui more user friendly and efficient
(having to create filters for spam already wastes enough of my time, the
e-mail client shouldn't make it take longer than it should).  Add some
hotkeys for the Add Criterion and Add Action buttons.  Make the criteria
list scroll when one navigates with the keyboard cursor keys.  Using cursor
up and down should scroll through each criterion, not move through the
fields for a single criterion left to right first.  This whole interface
should be easy to use without being slowed down by a mouse.


How often does this happen? everytime
