What does the tile spacing change do? Is this changing the actual spacing of the
tiles? Making these 2 changes should go through UI review as we had very precise
specs when we implemented it (ask bettes@).

I'm not sure why we had a max of 4 apps (that seems like an oversight), when we
had a limit of 5 here. I'm OK with increasing the limit to 8.

Yes, it changes the specs for tiles, so 8 tiles match the container nicely
(without leaving much space).

I looked at the Ares mocks, and I couldn't find detailed specs for the app
search list. Let's confirm with @bettes.

 const int kTopBottomPadding = 8;
