Last Active Tab Switcher

About

When you close a tab in chrome, you are dropped on the next tab to its right. This behavior has infuriated me forever since I switched from Firefox, and after waiting for years for Google to fix it, I finally created this simple extension. 

It keeps track of your recently active tabs, and when you close the current one, it will take you to the one that was active just before, not to the random tab you happen to have to the right of it. 

Additionally, if you `pin` this to toolbar, there will be a little icon, that you can click to switch to the previous tab without closing the current one (clicking on it again will take you right back). 

Right click on the button will give you a context menu with your recent tabs, so you can quickly switch to any of them. You can also click on "Open Tab Manager" to open a popup with a little more verbose description of the recent tabs with favicons etc. (you can also search it with ctrl-f). 

You can also use keyboard shortcuts to move backwards and forward between tabs in the history stack _without actually changing it_ (so that you can, for instance move a few tabs back, at a time rather than just alternating between two most recent once if you just click on the menu button). Clicking on tab tiles in the manager window also has the same effect (but clicking a tab in the menu _will_ put it on the top of the stack). Look at chrome://extensions/shortcuts to see/modify the chortcuts for each action.
