Replying to the list this time...
It cannot be done now (at least not really conveniently). I am coding a  
patch to do that and more. Here is the idea so people can comment on  
its usefullness/praticality.
I will allow the user to enter a "partial date" in the date fields for  
a date filter; that is you can ask balsa to filter between the  
following to dates for example (let's say this is in the US locale:  
mm/dd/yyyy):
*/01/* to */31/*: meaning filtering everything of the current month  
(stars are replaced by the corresponding fields (here month and year)  
of today's date.
You will also be able to use "offsets":
-1/01/* to */31/*: meaning last month plus the current one;
or also:
*/-28/* to */*/*: meaning the last 4 weeks
And any combination you can think of...
Advantages: completely backward compatible with the current filters as  
you just have dates strings.

Codewise nothing is changed for the API of the filters; you still have  
only to check the date interval (which is still given by 2 time_t's).  
This is achieved by computing the "partial" dates right before  
filtering (in the prepare_filter fonction). The only problematic (but  
already coded) part is about the locale legwork: from the canonical  
representation we use to store everything (yyyy-mm-dd) to the locale's  
one.
Basically alsmot everything works (I still have to worry about a few  
things for the computing of the dates but should be OK soon).
Comments?
