Derpibooru Buttons and CSV per Shnurks

This extension has two features better searching and easier downloading:

• It adds two buttons to your search bar, one to filter by upvotes and one for faves. They can both be clicked multiple times to cycle through "only", "not" and "either".
• When you right click an image it's id and timestamp will be saved to a CSV. You can copy this CSV to the clipboard by clicking the button in the top bar. It will also be logged to the console just in case you forgot to paste it and copied something else in the meantime.

If something doesn't work write a message on Derpibooru (https://derpibooru.org/profiles/Moonstrike).
