I don't think anyone has requested this previously, but I may stand corrected... :)
Floor Reflections : A Roughness parameter for glossy reflections with samples coupled with an IOR slider...
I am aware that geometry can be used, thats what I do at the moment, but it can be a little bit of a pain to setup on occasion
I'll give you a big +1 ;).
I'm using a flat plane model right now. Combined with an opacity map with a very smooth radial gradient it can give nice results, but I find the EV is often too prominent in the reflections. This makes the plane look like a dish. Sometimes this is OK, sometimes it is not so OK...

+1 :) - This has been requested a few times. I'd also like to be able to adjust IOR, add roughness and even add textures.
Personally, I've created a 6x6 square surface plane that I'll pull in and scale for the floor and/or as emissive light/reflection cards. It's quick and all, but sometime's managing the edge of the imported floor plane is a pain. I keep having to readjust it larger if I want a low angle shot but don't want to see the back edge of the floor plane. It'd be cool if KeyShot had a virtual floor that would blend into the horizon/at infinity and could take materials and texture maps.
Another nice prop is to create your self a "seamless" that gives you a backdrop and rolls into the table surface just like photographers do.
+1 "... It'd be cool if KeyShot had a virtual floor that would blend into the horizon/at infinity and could take materials and texture maps."
Yep, same issues here. A floor plane at low angle positions shows the edges, even when the plane is extremely large. I agree, it would be nice to have a built-in floor plane option that can be assigned materials just like imported geometry.
