About

WARNING: to use this extension you will need to manually edit JSON configuration. It will not break anything but is somewhat complicated.

The "Read your browsing history" permission is requested to read the current url address of the window in order to apply matching rules.

This extension can automatically arrange windows based on the settings defined in JSON. Before using it you need to open the settings page and fill in three configuration sections:
- actions
- matchers
- settings

At the bottom of the options page there are some examples - feel free to copy and paste them to the fields above and adjust to your own needs.

Please follow the documentation on github to configure actions and matchers:
