Advanced Search, Search By Product Features

OK so in upgrade many of my options were convered to variations, now got same name and not sure what products assigned to what.

If this

Advanced search, Search by product features

at least had # feature number it would be easier to search for what product assigned to what feature. How could I add code to some tpl to show feature number next to its name in advanced product search ?

Or maybe some other solution ?

As a workaround I have renamed feature with number...

and even so its a bug
