[Feature] Panels : expandable tree when choosing directory to add (alternatively current directory scheme used for navigation)
Is your feature request related to a problem? Please describe.
-> Currently when a user try to add a directory to a Panel a flat list of all directories, subdirectories of directories etc. is shown. When one has many directories finding the relevant directory can be time consuming.
Describe the solution you'd like
-> It would be nice to be able to have the directories/subdirectories displayed as an expandable tree : when one clicks a node of the tree (corresponding to a directory) all children of that node (i.e. subdirectories) show upon expansion of tree node
-> Alternatively one could have current directory scheme used for navigation (where only directories of current level are shown, and when you go into directory only subdirectories are shown etc)
-> An alternative would be to have a search box, where when you type into the search box, only directories containing the word are displayed (in realtime as you type)
