Group your tabs into groups.
Add a kind of panorama like feature to chrome (but less pretty).
This extention is design to people like me who always have a lot of tabs open at the same time. It allows the creation of groups (folders) to organise the repartition of your tabs.
With this extention, create groups and add tabs to them just with drag and drop.
Then choose the group of tab you want work with. You will not be disturb by the other tabs.
You can switch to an other tab group anytime you want.
Just close the group to close all the tabs inside it when you have finished to work with.
Now the extention keeps your pinned tabs open.
A git repository has been created. Fell free to fork or re-use it.
Some part of the code are in french though (sorry).
