Browsing the Library
The Problems page, without any filters, shows you the entire Stella library. Clicking on a problem's Stella number will take you to a page showing the contents of that particular problem. The solution is hidden by default, but can be revealed by clicking the appropriate button.
Advanced search filtering by Stella number or problem title is currently not implemented, but you are free to use your browser's search function to quickly locate a problem you happen to remember.
What is provided are filters for each of the three types of tags: Problem Set, Course, and Topic. Each is set to "All" by default, but you may configure them to your liking using the dropdown menus. Clicking the "Apply" button will reload the page and show only those problems that have the currently selected tags. Additionally, the links in the sidebar allow you to quickly filter by any single tag.
