Before you start downloading and installing every mod in existence, remember: Though none of these add-ons affect WildStar's content, they do affect the way you interface with its world. Many of these are convenient UI enhancements, but some could negatively impact your experience with the game if immersion is your number-one priority. Install at your own risk.
Speaking of installation, here's how to apply add-ons to WildStar: First, download the add-on you'd like to use from Curse. Next, extract the add-on folder from the downloaded zipped file. Finally, drop the unzipped folder into the add-on folder in your Wildstar AppData directory. This is typically located in C: [or whatever letter you've assigned to your primary hard drive] > Users > [Your Username] > AppData > Roaming > NCSOFT > WildStar > Addons. If you cannot see your AppData folder, you must first enable all hidden folders through the Windows control panel. If no Addons folder exists in the WildStar directory, simply make one, and you should be all set. Now, onto the add-ons--and don't forget to expand the images of each slide for a closer look at what's on offer.
