A feature that GitHub is currently lacking is the ability to save issue and pull request filters search pages. This app allows you to do that, and you can access them from anywhere since changes are synced across devices.

It improves the user experience for those with Github accounts as it allows them to add, delete, and rename filters

To add filters, you have to start with the page that contains them, then just look for the "Add an issue" or "Add a pull request" button. Deleting them is as easy as clicking on them from the search page while renaming the just needs you to toggle aalong the "name" field.
