[Plugin: NextGEN Gallery] Navigation prev next filter Bug

I am trying to change the text of next and previousa link in gallery pagination.

in nextgen-gallery/lib/navigation.php line 65 i saw the filters for next and prev links.

$prev_symbol = apply_filters(‘ngg_prev_symbol’, ‘◄’);
$next_symbol = apply_filters(‘ngg_prev_symbol’, ‘►’);

But the both are given the same name “ngg_prev_symbol”

so if i add_filter it get applied on both prev and next link.

$prev_symbol = apply_filters(‘ngg_prev_symbol’, ‘◄’);
$next_symbol = apply_filters(‘ngg_next_symbol’, ‘►’);

I hope developers will not it and fix it in their next release.
