Make infinite scrolling optional

Hello, I'm very new to the site so I apologize if this has been brought up before. I have a really slow Internet connection you see, it's the curse of living far away from civilization, smack in the woodlands. That my laptop is kind of over-worked doesn't help. Every time I get to the bottom of the screen everything freezes while the new posts are sloooooooowly loading. On a certain other normally infinitely scrolling micro blogging site I can solve the problem by disabling endless scrolling, so that I have more control over when more posts should load For example: while I refill my teacup and won't be staring at the screen for a few minutes anyway, and not when I was just about to open a new tab to check on some email. As imzy grows larger, we'll most likely get more and more content in our feeds to scroll through, and I'm sure I'm not the only one who could use a "want to load more posts?" break every now and then.
