JSON Window Manager is a free Chrome extension developed by Łukasz Gruszka. Designed specifically for Chrome OS, this extension allows users to arrange their chrome windows based on rules defined in JSON settings.

Please note that using this extension requires manual editing of JSON configuration. While it may seem complicated at first, rest assured that it will not break anything.

To get started with JSON Window Manager, users need to open the settings page and fill in three configuration sections: actions, matchers, and settings. These sections allow users to define the desired window arrangement based on their preferences.

For those who are new to JSON configuration, the options page provides some examples at the bottom. Users can freely copy and paste these examples into the respective fields and customize them according to their own needs.

If you're looking for a way to efficiently manage your chrome windows on Chrome OS, JSON Window Manager offers a flexible solution. Just be prepared to invest some time in configuring the settings to suit your preferences.
