Small extension that will zoom page (150%) when user clicks on left window border (red stripe on hover) or perform double right click.
Another click will zoom back to normal.
Point is to have fast click zoom without aiming toolbar buttons, O-menu or something like that. Simply drag cursor "far left" and click (or 2xRMB).
It also zooms iframes which is useful for comments with small font size (facebook, disqus...)
From version 2.5 works as a browser zoom (opposite css style)
Idea came from "Close tab by left border" Chrome extension.
If you need close tab functionality in the same way, I recommend you look for it on Chrome web store.
I just think this functionality is more useful.
