I've been doing some quite involved work on a site where we want to restrict user access to certain asset paths. Following the post at Assets Folder: Images don't show up I was directed to the excellent add-on, AssetSubfolderAccess
After hitting a few bugs think have resolved but this only works in the Assets tab/are of the Control Panel. It does not seem to work within the Assets modal (eg when prompted on entry creation/edit). Is there a separate hook available for asset modals or can anybody suggest an alternative way of targetting specific asset paths at specific users?
