Is it possible to make feature requests for Treehouse?

I was wondering if it was possible to make our voices heard with feature requests that the community could potentially benefit from when using Treehouse. Here's my two feature requests that I would love to see. Might not be alone in expressing an interest in having these embedded within the product.

1. A directory in Workspaces where we can organize different workspaces into different folders. Would definitely be useful so that I could organize different courses into different categories.

2. A 'Try Again' feature for Quizzes. Sometimes when I get the answer wrong to certain questions asked on quizzes, I'd love to know what the actual answer was instead of moving on to the following questions without new knowledge which might have been useful.

Thanks Treehouse for this great product that's empowering so many people :) I truly laud the efforts of the team behind TH.
