Ok. Took a new picture now, cropped it with paint instead of photoshop and seems to be working better, noticed that PS changed the colors quite a bit.
What would make the script even more perfect is if you could add in editable random "breaks", short and long. Five minutes here and there, and as you continue to stack up hours, longer breaks and more frequent short breaks if wanted, etc. All configurable per user's own requirements ofc. Would be awesome ^^
