For $15 You Can Have an Opacity Slider in Lightroom

Being able to adjust the opacity of adjustment layers is one of the many reasons I choose to use PS over LR... I can't imagine NOT having this option.

That's pretty cool...

I was looking into this and there is currently a $5 discount, making it only $10!

You can use the code launchparty and it is listed on the top of the page. I'm not sure how long the launch discount is good for, but I plan on purchasing this as I am just starting to learn how to edit in Lightroom and think it could be incredibly useful!
