UI suggestions

[alustig3]

I had a couple of minor UI suggestions. These are nit-picky, so please feel free to make them low priority / ignore :)

• In the mobile view, you can easily reset the search and funding status filters from the project page, but to reset the tag filter, you must first open the tag filter sidebar. It would be nice to have a tag filter reset button from the projects page
  

• In mobile view, I didn't realize that the funding status dropdown was a multi-select dropdown My expectations when selecting a dropdown is that I will make a single selection and then the dropdown will collapse, so when it didn't collapse I thought something was wrong. Eventually I realized I could highlight/select multiple options. Maybe instead of just highlighting the selection, it would be more obvious if there was also a checkmark or something?

• In light mode, it wasn't obvious at first that the GitHub readme was a clickable button/tab. I think because maybe the border is too thin or because there is no background color to contrast with its surroundings? It is much better in dark mode.
