Folders to manage and sort dashboards

We have more than 100 dashboards and it is not easy to navigate and fin the one we are looking for. We do use the search and add some dashboard in "favorites" to keep them on top of the list, but having a folder structure would be much better.

There's a related post, in this forum, about hidding dashboards from the drop down list.  Having folder would solve this as unused dashboard created by Brightgauge could be moved to a specific folder.
