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!
At its core Seshy maps windows to bookmark folders and tabs to bookmarks. Being able to store sessions as bookmark folders and bookmarks allows them to be closed and re-opened later and also means they sync to your other devices (assuming you have Chrome installed and bookmarks sync enabled).
There are plenty of oustanding issues for new features and improvements, feel free to raise a PR against an existing issue or create a new one but note that it is encouraged to use discussions for new feature ideas rather than issues.
