Hard to push next post on touchscreen

The buttons that navigate inside of PARS (especially on the top bar) are very small, and very close together. With a desktop, this is no problem. But if you're on a device whose screen is its pointing device, it makes these buttons very hard to press.

Suggested edits: Make the buttons slightly larger. And/or make the buttons slightly further apart.

Expected result: Navigating through posts on a phone or tablet will be significantly easier, without drawback.
