[imp] Filter Link or Menu

[Tim]

Hello,

I am new to IMP and in the process of testing it for our system. After 
reading the help file, it appears that there is a link or menu for filters. 
However, I do not see anyway to access this filter management. The only 
filter option I see is a small icon next to the Inbox label that Applies 
the filters.

Is there supposed to be a filter management section? If so how does one 
access it? I have checked all preference files and no filter options appear 
to be disabled.
Thanks
Tim
