When creating a lense with "only results from sites", it would be nice if there was a way to assign weights to the sites just for searches with that lense. This would be useful for lenses where you'd have some highly specialized sites in the lense where you'd always want to see results, if they exist, from those sites first, but you also include a bit more spammy sites.
I imagine, maybe on the lense creation site, instead of having a single input field for all sites, you could have an auto-repeating input field with one site per row and behind each row, you'd have Normal / Raise / Pin settings for that URL, which then only affects usage of that lense.
