Mystery Bar

[Alerith]

I don't want to go on any huge theories here but... in the 2.0 screenshot they have revealed, I'm having trouble identifying a few things.

To the left of each person's name, in the party window, there is a bar that seems to be filling up, and above it says 'T1' 'A2' 'B3' A4' 'C5' 'A6' 'T7' 'H8'.

My personal speculation would be some sort of Limit Break bar or something. I also have no clue what the letters and numbers mean. At first I thought coordinates on the map, but a lot of those players are really close to each other.

On the other hand, the numbers match the numbers next to their LS symbol.

Second is the bottom right. All the colored squares. I'm at a complete loss and don't really have any theories.

Now, under some of the skills in the skill bar, it has a TP cost listed. But on some skills it has what appears to be a cog symbol.

Everything we think up is speculation, but I'd like to know what ya'll think some of these mystery elements are.
