Styling the Group Events page differently

Question from the Community Board re-posted:

I wanted to know if there was a way to style this differently (e.g. list of events vs the calendar view or maybe only one month vs the side by side) and if there was a way to remove one of the prev/next controls (they are on the top and the bottom.)

I thought there might be a way to do this via settings, but I'm not finding it.

I also wanted to style the "Add event' link to make it look more like a button (and stand out more.)

UPDATE: I tried it via the settings, and I'm wondering if the theme in use on this site is overriding.
