Open Stack

This simple but effective tool went straight into my personal list of daily
most used utilities since Daniel suggested it to me some weeks ago.
I’m using it mostly on OS X and it works smoothly. Dan sorted out very quicly a
couple of minor bugs that came up during initial testing.

It proved to be particolarly useful while tracking the status of all the Hyper-V
pending patches that we had on the Havana and Icehouse backports.

Since then I use it constantly to track my co-workers patches and reviews and
keep an eye on the CI failures as frankly beyond a given volume emails are 
simply too noisy, no matter how many filters you set.

All in all a simple productivity saver, it’d be great to have similar features
directly in Gerrit.

So, thanks again! :)
