Responsive

Sure, I was playing around with more or less descriptive text.

Only put anything in them if your theme is responsive (if it’s formatted differently, say, on a phone than on a laptop). If you want QuickShare to take up less space on smaller screens, you can set sizes where that happens. To test, I recommend trying roughly 600px for force-small and 400px for hide, then reload the site and resize your browser window down until it’s narrower than those values; you should see the changes happen. Then it’s just trial and error to determine what works best with your theme.

For many themes (especially older ones), it won’t make sense to use this option, but it’s useful for modern themes. Ideally, you should also see how it looks/works on a couple of mobile devices (smartphones/tablets), but the browser resize trick is a good shortcut. To reiterate, it all depends on your theme and your preferences.

In the next update, I’ll hide that option if the icons are already small to reduce potential confusion.
