No filters in Add/Remove utility

Hello,

I was wondering why there is no 'installed programs' filter, or for that matter any filter, in the add/remove programs utility. In gNewSense you can filter your programs just like in synaptic, which comes in handy from time to time. Is it possible to include it in the next distro or can I perhaps enable that feature somewhere in the configuration editor?

Greetz,
