I think a Sage Days dedicated to representation theory might be a good
idea,
where the goal would be to implement: computation of the representation

of finite groups, finite semigroups, finite dimensional algebras

Would this be an interesting topic for the Sage days at CIRM in March
2010? Or do you think this is too far ahead?
I was under the impression that it was supposed to be more of a Sage
School rather than a Sage Days
I think a useful thing to have in sage would be mutations of graphs
(which occur in the theory of cluster algebras by Fomin and
Zelevinski). Bernhard Keller has written a java applet (and
application) to do this which is widely used.

Can you elaborate on this? What do you mean by 'nicely wraps'? I wrote the
ClassFunction class that wraps GAP's ClassFunction command, but I'd like to
know what more could/should be done. I am not a GAP expert so the code
would definitely benefit from someone more knowledgeable about GAP

Two or three things:
1. Rational conics. Magma first implemented my algorithms, which are
in eclib but not wrapped, so we could do a lot quite easily there.
But now Magma uses Denis Simon's algorithm which is better in certain
cases, and he would certainly donate his code (in gp I think).
