Excellent, does exactly what it says it does - creates awesome screenshots. So easy to use, no messing about with [Ctrl] + [PrtScn] and paste to paint then save as etc.. yawn..! Just select the type of screenshot you want, edit if necessary (If you adjust your screen size 1st you don't have to do that!) click download and it names the file automatically ready for use.
Note to dev's: Please do not change anything, it works just fine as it is, if you feel like you need to make an improvement, just ask a colleague to slap you round the head - seriously do not change anything!
