Thank you, every update is very welcome!
HOOK version 2.02, now still needs up to 6% CPU in the background (!) – therefore I downgraded it again to 1.8.
CPU usage counts a lot since it adds with every single process in the background to the overall system and version 1.8. is extremely nice / low on CPU with 0 to 0.5% in the background
