@nandy-andy @rogatty Guys, this is a script mostly written by Rafał - please code review it and we could test it when it reaches QA column. Adding @aquilax here if he doesn't mind taking a look :) :8ball: :snowman: :bird:
I was wondering if we need parseInt here. It's surely safer, i just assumed i will know what i'm triggering when running the script. Will make the change though, let's be safer ;)
