This was asked for a long long time ago, and I would still really like to get this feature. The comparison table is currently very difficult and frustrating to use since it puts all of the phones in the table at once. And of course there's no horizontal scroll bar at the top, so you have to do many steps of down, right, up, down, right, up, etc. to look through some of the upper details on a few phones.
Pick specific phones instead of all for the comparison table
