Hi,
This generic iteration action will be very useful. It simply iterate between a start and end integer, you can then do whatever you like during the loop and act based on the current index.
[EDIT]
It can count up and down ( if end value is less or more than start value), and you can define the increment step, for example you can increment every 2, instead of every 1
Also found a small issue where the action would not go trough the first value, this is now corrected and will properly start at the start value, instead of start value + increment.
