Recent Forms is a feature designed to save you time. Any time you launch a form or bundle of forms, those forms will automatically be added to the Recent Forms panel on the Dashboard under the Resume Workflow section. The next time you need to launch those same forms, you will not need to perform a search--they will be displayed on the homepage for easy access (even after logging out and back in). Just click on the form(s) you need--to add them to your cart--and you will be brought directly to the Add People page for prefill.
Recent Forms are a great way to speed up the form selection process, especially if you happen to use the same set of forms often in your day-to-day work.
