About

This extension allows you to add per-domain custom CSS and JS. It stores those settings locally OR in your Google profile, depending on the setting per site.

It's a combination of:

* StyleBot, but adds JS and a much simpler UI
* Personalized Web, but adds online storage and a browser action button for easier access

It does:

* add CSS to any domain
* add custom JS to any domain
* add custom CSS to the extension's options page (in case you don't like my UI design skillz)
* store your settings online (optional, connected Google Drive)
* export your sites to JSON format
* import your JSON with UUIDs, so you can sync manually between computers or as backup
* have a simple UI that saves with CTRL+S or ENTER and a browser action button to point to it

It does NOT:

* add a slick DOM element selector tool like StyleBot
