Extension: Tabs MRU
Developer: Puiu Hrenciuc
Current version: 0.1.5

Description:

Hi, my name is Puiu and I am using Chrome since first version came out.
Unfortunately there is a little feature missing in Chrome with which I got very
used to in other browsers like FF or Opera. This little feature is called MRU
tab navigation. In FF or Opera, when you hit CTRL+TAB to move to the next
tab, the browser actually keeps track of the order in which you visited the
tabs and you actually navigate backwards. For example, if you have 10 tabs
opened, but want to cycle between two of them, you can do that by just hitting CTRL+TAB.
Sadly this feature was not implemented in Chrome, so if
you want to cycle through two tabs you have to cycle through all of them
(unless they are near each other and then you can use CTRL + PGUP/PGDWN).
Since I knew that Google Chrome developers marked this issue as "will not fix"
and since there were no such extension yet, I thought I should develop one
and since I saw that there are requests for such a feature, I thought it would
be good to post it here. Any feedback is greatly appreciated.

Features:
- adds MRU tabs switching by using CTRL+` combination

Known issues:
- CTRL-TAB behavior can no longer be changed in Chrome using extensions
so the key combination was changed to CTRL+`
- since I didn't found any way to set global hot-keys in Chrome, I had to use
content scripts to make it work. The issue with content scripts it that they
work only on http:// https:// , so in other words, the CTRL-` will not work
correctly on other schemes (i.e. chrome:// pages). Fortunately I rarely use
those pages and after all this is just the first version. Hope to fix it in a
future version.

Tested on: Chrome 4.0.249.78 and 5.0.307.1 on Windows 7 and Ubuntu
