Window and Tab manager for managing multiple open tabs and windows with simplicity.

Cluster is a window and tab manager extension for Chrome that helps you manage multiple open tabs and windows while using minimal system resources. 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.

Features include undo removed tab or window, sorting windows tabs for better overview, showing the real tab URL when using the Great Suspender, launch the manager using keyboard shortcut, option to save or restore sessions from the manager or drop-down menu, search and filter for tabs by title or URL, easily move tabs between windows, suspend all windows tabs, and more.

Cluster is built to be fast, simple and uses minimal system resources to not get in its own way. A great tool for taking control of your browser sessions, keep things organized and free up memory.

Sync your saved windows across multiple machines, requires a one time fee license that helps support Cluster development and cost associated with third party services.

It's that I want

I am a tab hoarder, ADHD person and an extreme browser. I use anywhere from 50, to 4000 tabs. It's a curse and this plugin makes it easier to close tabs I KNOW I should've closed.

The search at the top is powerful, the ability to close only the search results is wonderful, it's fairly fast.

I use this in conjunction with several other tab management tools but this thing really helps me clean out hundreds of tabs I could've closed, without accidentally closing hundreds of ones, I did genuinely mean to get back to.

I can't recommend it enough, infact I clicked the about link to find a spot to donate, thank you for 'getting it right'

I love this app but I can not emphasize just how much I detest the "close window" button (per "current window) in the active Windows tabs.
I've lost countless WINDOWS of hundreds of tabs, because of this button, far too close to another X, without an "are you sure" - it's the only flaw with this software.

I've emailed them, I'll paypal $20 to disable it, it's bad bad bad design.
