Clicking Themes in Themes section

I’ll make this short and clear:
I suggest that Theme section have the preview-image(s) show a popup for previewing the theme while the link of the theme below that image automatically selects + uses the theme.

I’m getting sick of having to click the image/link and then “Activating” it when I don’t even need a preview (i.e. I know how it’ll look/used it various times before).
