Fewer tabs, more focus.
Having too many tabs open is bad for your productivity because you waste time looking for the tab you need.
Rather than having one Chrome window with lots of tabs its better to have many Chrome windows with only a few tabs each. Each Chrome window can represent one task that you are working on and have only the tabs needed for that task. In Seshy we refer to each of these task contexts as 'sessions'.
Whilst you are working it should be effortless to create, name, and switch between sessions. It should also be quick to close sessions you are no longer working on and re-open them later. This is what Seshy does!
