Thanks to last Photoshop World Codeathon in Las Vegas, we’ve finally broken the 4 Color Samplers limit in the Info Palette – we’re allowed to scatter up to 10 of them like a machine gun (provided we’ve Photoshop CC updated to the 14.2 dot release, available from Jan 16, 2014 onwards). If you’re in the color correction business, that is a big deal.
[Fireworks popping, people getting naked, etc]

Now, to be fair, this is a pretty old feature request (ignored/postponed…) – something more like a JDI if you will.
But let’s not be the usual mumbling guys for a little bit! Just a little bit 😉

PS
I built an experimental Panel back in 2011, called Power Info Palette – which still shows that there’s always room for improvement! But it’s definitely nice to have native support for 10 samplers in PS now.
