If you're looking for a timesaving screen capture application with unusual features, give Voila a try.
Its superior image editing tools and more precise parameter controls put it easily over the top.
If you do a lot of screen captures, edit those captures using PhotoShop or other editing applications, then Voila is definitely something to consider to help streamline and optimize your workflow process.
There may be other tools for capturing screenshots but Voila puts a very useful toolset into a lean package that will run in the background without bogging your system down.
Voila is perfect at its job, and has definitely caused more than one moment of surprise during the time I used it.
