I'd love the option to manually organize my sites in the dashboard. I find that I am working on a site at a given time and want it to show up first for a given 2 week period but I may also make changes to other sites during the same time which would bump them up if I organize by last modified. I'd love to just be able to manually put a site where I want it.
I'd also love folders for older sites or templates that I use to start sites.
Hopefully others will want this functionality also and the Webflow team can make it happen!
