There is a case for you to start using AuthorCafe well before you actually start writing your research. Get the building blocks together and let your co-authors bring their own building blocks. Together, you can keep building, preview them, study them, extract content and assemble your paper.
When a project has more assets than are in use, select them and Hide. And declutter.
When a project needs an asset from another project, borrow with ease. Search assets under All Projects, or a specific project, and pick from the list to show the asset in your current project.
You have x number of assets to allocate and reallocate across y number of projects. You need to delete some assets and import new ones. This is all done with ease under My Cafe > Asset Master. Here, you see your assets classified as Used/Unused. You can move Unused assets to the trash and assign Used assets to other projects.
