This would be very helpful yes. /signs on the list.
It should also not be hard to find since its allready possible to find the xp (in percentage atleast) manually.
I dont remember the exact command, but its something like /listvars or /varlist or whatever. it dumps a large amounts of variables to your chat window. If you then do /listvars adv youl see your XP in percent (to next level).
For example 200/2000 would mean you have gained 10% so far of current level.
Given this, it should be very easy to locate that in memmory, atleast based on what I know about how you track these things.
WyvernX, would you add it for us pretty please? it would let us do all sorts of cool things like make scripts that estimate time level to levelup ect.
You can still do this now, but that involves reading all the pixels in the XP bar, and thats cumbersome, indirect, and more prone to incorrect results.
