@WIZARD The recording scripting mode is part of the OFS Software. You should post your request in this topic. Or even better, create an issue/feature request directly on the github page.
For the MTFG OFS Add-On I would say that it is not possible to use the mouse wheel for input with a reasonable amount of effort. (This Statement only apply to the MTFG Extension). Reason: The mouse wheel is bound for zooming in opencv windows. To disable this behavior i have to adjust and compile opencv myself. But that would not be worth the effort…
