Cluster also comes with the tools for quick navigation to open windows and tabs, and a tab project manager to easily save and restore windows and tabs sessions as working projects.

Restored windows launches each tab in a suspended state to minimize the load time when opening lots of tabs at once.

User reviews

All of sudden the "Saved Windows" keeps loading for like 1 minute then poof. All is gone

I was a paid user for a long time, but the domain seems to be expired or non-functional (clusterwm.com) and emails for support bounce back. This plugin was great for a long time, but I believe it has been abandoned. Beware that sometimes the plugin deletes a tab group during a rename. Also sometimes it doesn't synchronize across systems, or when it does, it overwrites groups that were saved there without checking it first. I gave 2 stars because of how long I used it and how much I enjoyed it over the years. If the current maintainer contacts me, we can discuss these issues and I will consider changing my rating.
