Each workspace could contain all the resources (i.e. bookmarks/extensions) you need for that particular area of your life.
For example, let's say you have a school workspace, a hobby workspace, and a gaming workspace. In your school workspace, your bookmark bar has your school website, Canvas, Google Drive, etc., and can hold any articles or resources you need for school.
For the hobby workspace, you can keep bookmarked supplies you need to order regularly, inspiration, and even side hustle tools if you have an Etsy Shop or blog.
For the gaming workspace, you have all of your online games, guides and walkthroughs, or gaming news sites.
Each workspace is distinct, so you can keep each area of your life distinct. You can focus on one at a time to boost productivity, keep everything organized, and manage your resources easily.
