I do think simply calling that option "Filter" is a little weird. How about labeling the blend mode drop-down as a whole "Filter", and changing the "Filter" option to "Custom..."? That may be a better description of what it does, and then it would make sense to put other filter presets there too.
(Instead, the composite modes should be added there, as Niko suggested.)
I would also like to see some feComposite presets in that list.
This list, like the Blur slider below it, must search the selected object's filter stack for feBlend or feComposite, display the current mode of that filter and let me change it (or add a new filter to the top of the stack, but only if no such filter already exists in the selected object's stack).
That would interact very badly with many interesting filters, as they may be built out of multiple feBlend/feGaussianBlur elements; simply picking the first or last feBlend element (or even all of them, depending on how the filter is designed) won't give desirable results.
I think it is best to only allow the direct feBlend/feComposite/feGaussianBlur manipulation when the filter conforms to some explicitly recognized pattern.
