I spend a lot of time trying to find just one tab out of the dozens, just kidding, it is hundreds, of open tabs.
Same thing happens with terminal windows and folders so I'm hoping to get this tool functional for all of those things.
At the moment it works for Firefox (with the accompanying extension) and soon Chrome as well.
It's a complete hack of code (but MIT!) and the security side is a mystery I'm slowly unraveling..
But it does feel really good to use. Eventually this stuff will just be everywhere, I just couldn't wait any longer.
