The ability to search TRIP and then filter by publication type (e.g. systematic reviews, guidelines) is often cited as something that's really positive about TRIP. Aside from the addition of a few new categories there have been no real changes to it since it was introduced (probably ten years ago).
While it works really well, I'm wondering if it can be improved. In the image below (a mock up, it's not real) you'll see a potential feature is displayed if a user clicks on the 'Systematic Review' filter - it allows you to select separate publications with the systematic review category.
