So if you're like me, you'll use a plethora of web apps in your day-to-day work. I hate browser tabs general, sometimes there's just too many.
I managed to stumble across Fluid App - it allows you to create custom Mac apps from your web apps.
Just install the app, feed it a URL, the icon is driven from the favicon (I've had to customise all of mine for retina) and hit create. It creates a little package and moves it to your Applications folder.
Now you can launch the app like any other software and bypass the browser.
Well worth the $5 for the license too.
Check it out.
