Hmmm. Good timing. I was messing around with this just yesterday.
Windower4\addons\pointwatch\data\settings.xml
there will be a line that looks like this.
Code
<default>xp.current..'/'..xp.tnl..'XP '..lp.current..'/'..lp.tnm..'LP ['..lp.number_of_merits..'] XP/hr:'..string.format('%.1f',math.floor(xp.rate/100)/10)..'k '..cp.current..'/'..cp.tnjp..'CP ['..cp.number_of_job_points..'] CP/hr:'..string.format('%.1f',math.floor(cp.rate/100)/10)..'k</default>
Replace it with this one.
Code
<default>xp.current..'/'..xp.tnl..'XP '..lp.current..'/'..lp.tnm..'LP ['..lp.number_of_merits..'] XP/hr:'..string.format('%.1f',math.floor(xp.rate/100)/10)..'k '..cp.current..'/'..cp.tnjp..'CP ['..cp.number_of_job_points..'] CP/hr:'..string.format('%.1f',math.floor(cp.rate/100)/10)..'k '..sparks.current..'sparks '..accolades.current..'Acc.'</default>
Now, it doesn't display per hour sparks/accolade gain or anything. The addon just doesn't have that option built in.
But this will display your current sparks and accolades at the end of the usual pointwatch info. I didn't bother with putting /50k, cause I know what the caps are. don't need it on there.
