Is there a global variable like {ifThereAre filters}?

Hi,

The variable {ifThereAre filters} doesn’t appear to work outside of the filter panel but I was wondering if there’s another way of checking (in the header) for active filter options on any of the listing pages?

I would like to prevent the left column from being rendered on pages without filters.

Any update on this as I really want to roll changes to our site overnight and I would prefer not to jump through hoops if I don’t have to.

Edit: Actually disregard this as I’ll just change the column widths with some inline css to avoid the hassle.
