S3cret i'we kinda edited your tool and added some stuffs. I think you should add 1 more statistic to your tool so it would calculate the time needed to lvl up in hours the code is below
Code:
$curexp = _MemoryRead($offset_curexp, $mem)
$nextexp = _NextExp(ControlGetText($handle, "", "[CLASS:Static; INSTANCE:" & $instance_level & "]"))
$expp = Round(($curexp/$nextexp*100),2)
$nexp = (100-$expp)
$xph = StringTrimRight(ControlGetText($handle, "", "[CLASS:Static; INSTANCE:" & $instance_xphour & "]"),1)
$time2lvl = Round($nexp/$xph)
If GUICtrlRead($timetilllvlup)<> $time2lvl Then GUICtrlSetData($timetilllvlup, " "&$time2lvl&" h")
It will return the time needed to lvl up in hours. just don't get scared at higher lvls by the time needed like i do ;)
And i suggest you remove the black background ,altough it looks nice because its flickering, try white background with blue text like in sbot
