Few months ago I have asked you about technical details of my idea (stop effort when laptop goes sleep, resume when laptop is resumed).
Here is result of my work - patch in code, and 2 files:
This patch is against 0.70.0 . I tried to apply it against 0.73, but seems that you did some revolution in gui code, so I can't do it quickly.
No choosing it in preferences ... in fact, it's a bit quick and dirty (but works for me :D). I hope you will find it usefull, and do something nice based on it. If not, and you need from me more mature patch, let me know, I will try to polish it a bit.
