We often allow our clients to view the overview view of a folder and often times they are wanting to share a web resource with us, but they have to email it to us in order for a member on our team to add the link to the Bookmarks card. This is just an extra step and out of the way, way to do this.
So instead we've been using Google docs as our "homebase" since everyone, team members and clients can add links there. Though, it would be nice to have all relevant links for a project all housed in ClickUp.
