As our company admin for Smartsheet, I typically deploy all-new Project Workspaces - this provides me with the opportunity to assist team members if they become stuck, or have an issue; I can then problem-solve with them within their workspace.
This leads to an issue where I have many, many Workspaces visible, of which I really only use 5 for my own projects regularly. Typical issues that arise are;
I believe an easy way to resolve this would be to add a Filter in the Search bar that allows the user to select only the "Favorites" Workspaces as I've suggested below. (I'm unsure how the Linking from a Cell feature could be treated, but this would be a start).
However, ideally, I would like to be able to Hide the other Workspaces from any view - unless I specifically need to call one up to interrogate with another user.
