Feature Request - increase the size of the file preview in the project window

[merlinbug]

When previewing files in the project window, the size of the preview screen is very small and makes it hard to see. It would be great if there was a way to increase the size of this window so that you could quickly cycle through the files and pick whatever you needed at a glance. I know you can double click the file and it'll show up in its own large window, but this is time consuming and not super practical.

In this case I'm dealing with doezens of files that are just rough sketches, and they're really hard to distinguish from one another as small previews.
