The Future
The following general direction for the future of modular forms in SAGE.
-  Speed up the linear algebra even more, especially over number
fields.  SAGE now uses the highly optimized
IML and Linbox libraries; use even more of their functionality. 
-  Add computation of q-expansions of half-integral weight forms using
the algorithm in Basmaji's thesis.  This is a 1-page program. 
-  Include Kevin Buzzard's table of weight 1 forms.
-  Greatly extend what is implemented for computing directly
with modular forms without users having to know about modular symbols.
-  Much more functionality for computing with the method of graphs.
-  p-adic Modular symbols ala Pollack-Stevens (Robert Pollack has discussed
with me implementing this or "guiding a student" to implement this). 
-  Quaternion algebras
-  Hilbert Modular Forms, Siegel modular forms, etc.
