I kinda liked this, so I tried to make something.
5 dots at intervals of 15, 30, 45, 60, 75
You can change 15 to like 10 for decreased intervals.
CODE
$ifgreater(%play_counter%,89,$repeat(•,5),$repeat(•,$div(%play_counter%,15)))
If you want dimmed dots then this kinda works, couldn't figure how to make it subtract the right number so it just adds it, make sure you limit your column width so you can't see more than 5, maybe disable elipsis too.
CODE
$puts(auto_rate,$ifgreater(%play_counter%,89,$repeat(•,5),$repeat(•,$div(%play_counter%,15))))
$ifgreater(%play_counter%,89,$repeat(•,5)$repeat(825E00|D79B00•,$sub(5,$get(ar8))),
$repeat(•,$div(%play_counter%,15))
$repeat(825E00|D79B00•,$sub(5,$get(auto_rate))))
EDIT: use %play_count% for new beta. thanks unabatedshagie
