Modify the xp tracker top screen

[eifos]

Hello,

I would like to modify the xp tracker in the midlle on top of the screen (the blue bar that shows paragon and time to next lvl).
Now it shows xp/h for all characters gained today, i would like to change it to the current character and to xp gained this run.
You have that in the bottem right if you open it but it would be handyer if i dont have to keep opening that screen and get useless xp/h rates on top if i went keyfarming or anything like that.
So snippet/plugin writers pls help a programming noob out here
Thx in advance
