liveEditExp.lua

--[[

On the warrior 'list', select a warrior in the list (don't actually click through to their page)
Run the script and the values should be shown on screen.

LeftArrowKey = decrease exp once per click
RightArrowKey = increase exp once per click
K = decrease exp once per frame while key is held
L = increase exp once per frame while key is held

To update the displayed link value, click the down then up arrow to deselect and reselect that pokemon.

I have already used this to get the exact exps for link X.00 values if this is what you want
