I love having the app instead of website. But, it's super slow. Is it possible to cache specific spaces or "sections" of the product? If there was a "keep on my computer" button/check-box that would always download and keep certain areas on my computer, it'd be WONDERFUL!

This would greatly improve performance. It would download my cache selections upon bootup/powering on and launching and be ready for my work when I am. Of course, any changes I make would be quickly saved to my cache (the backend would sync to the cloud)... this would make the app snappy, responsive, and much easier to use.
