I use Raindrop as a research/design tool, and would love to have a temporary collection where I can “triage” bookmarks from a few folders without having to take it out of its original folder.

I’m a product manager, so when I work on a new feature, I want to be able to grab links from my “Design” and “Code” folders, and amass it into one custom workspace just for that project purpose, so that I can share it with team members as well and get us all on the same page.

Sometimes we also do workshops, so if I can select a few images from the links I have saved and "pin" it to the workspace, and print it all at one shot, then it helps me bring it offline as well.
