Scale Interface for Hi-res displays?

I'm trying to get C2 set up properly on my Surface Pro 4, but a lot of the interface (icons in panel bars, collapse/expand in the events/actions, etc) are so tiny that they're VERY hard to interact with. Is there a way to scale these icons so they don't look like they're about the size of an ant's leg?

You'll probably have to check the window size and have a global scaling factor to resize everything with.
