This feature was recently added thankfully, it was something I requested.

But I'm not entirely sure how to use it. For example when it asks me to specify a screenshot filename, does the name matter? Will it increment on the filename if it already exists? Such as "Picture01.png / Picture02.png" etc? Also do I need to specify a directory for saving or filetype etc?

I don't suppose someone could whip up a quick and dirty tutorial for me to try out?

Thanks
