Column width vs. thumbnail size – please add both to configuration

Hi,

I’ve changed split of columns (*), and now Featured Image is scaled up from thumbnail which is only 700px wide and looks awful.

I’ve changed thumbnail size hardcoded into functions.php (**), but it’s not elegant and I’d have to changed after each pinboard upgrade.

Could you add both values as configurables to Pinboard?

(*) Done that via custom CSS in Theme Options -> Layout:
#sidebar { width: 20%; }
.twothirdcol { width: 80%; }

(**) unified diff:
