does something like %foobar_path% from Panels UI exist in Columns UI?
What for? I can't see any use for it in the stock panels, you could ask the developer of whatever (panel?) component you think needs it.
i wrote about it here (last few posts)
but this is probably a limitation of trackinfo mod or has something to do my current configuration :/
edit: i'm experiencing the same thing with Panel stack splitter:
$puts(foodir,C:\Media\foobar2000\)
$puts(arttop,-8)
$puts(artleft,0)
$puts(art_w,350)
$puts(art_h,323)
$puts(cover_w,298)
$puts(coverleft,$add($get(artleft),40))
$puts(covertop,$add($get(arttop),12))
$imageabs($get(artleft),$get(arttop),$get(art_w),$get(art_h),$get(foodir)fb2k-buttons2\cover\cdcase-noshadow.png,)
$imageabs($get(artleft),$get(arttop),$get(art_w),$get(art_h),$get(foodir)fb2k-buttons2\cover\cd.png,)
$imageabs($get(coverleft),$get(covertop),$get(cover_w),$get(cover_w),$replace(%path%,%filename_ext%,folder.jpg),nokeepaspect)
$imageabs($get(artleft),$get(arttop),$get(art_w),$get(art_h),$get(foodir)fb2k-buttons2\cover\overlay.png,)
when i use $puts(foodir,) or $puts(foodir,.\) or $puts(foodir,./) only the third image shows (the cover art) when foobar starts. but when i go to settings and press apply other images show up.
not sure that this is the place for discussion, but i am having the same problem with PSS and trackinfo mod.
