Igno-KS от TomTrustworthy

Adds an 'Ignore' button to each project tile so you can hide specific projects.
Hidden projects are replaced with a placeholder showing their name, ignore date, and a button to unignore.
Projects are automatically unignored an hour after their campaign ends, based on the time left shown on the project.
You can manage your ignored projects from the extension popup, where you can unignore individual projects or all at once.
The extension only runs on Kickstarter-affiliated pages and does not track or store data outside your browser.
This extension helps you focus on the projects you care about and keeps your Kickstarter browsing experience clutter-free.
