S4T - Shortcuts for Tabs

About

Extension to add some some shortcuts that i find useful to manage tabs and tab groups.

I use tab groups to organize my open tabs. It would be useful to have a way to collapse/expand all the tab groups or collapse/expand all the tab groups except the one that has the active tab. How about be able to expand/collapse by tab number? or cycle throughout the most recent view tabs?

Alt + Shift + Up:            Collapse all tab groups except the active one
Alt + Shift + Down:       Collapse all tab groups except the active one
Ctrl + [1-9]:                    Toggle the Nth tab group (by position) collapsed/expanded
Alt+W:                            Fast MRU tab switch - cycle through recent tabs quickly

Other shortcuts added that i found useful:

Alt + T:                          Open a new tab to the right of the current tab
Alt + Shift + T :            Open a new tab to the left of the current tab
Alt+Shift+R:                 Close tabs to the right in the current tab group
