I'd like to be able to work with more than 1 feature in more than 1 layer in the popups. Now I can select multiple features in a popup, but only from the same layer, not from different layers. And when I click the "Toggle selection" button at the bottom of the popup, it only seems to take 1 feature into consideration, even when there are several selected. I'd like to toggle the selection of several features in the popup at once.
