This is such a simple extension, but so useful! I deleted it last week, thinking I didn't really need it, but I soon missed it. After a week I ended up reinstalling it for quick access to my recently closed tabs.

Can you change the color of the logo? Current logo color is purple when using the default theme 'firefox Alpenglow', which has a very low visibility.

can we got option for left click function? we don't always want undo the last closed tab and using the right click, mix list of the closed tab with the menu option...
