Okay, I think that fixes it! I will probably evolve this a bit further, but here is the code now: https://gist.github.com/arrowtype/a3c4445cd6b9a6174f885eccff38e1c9 (Caveat: Not sure whether it would work for UFOZ)

hello @JustJoeDesign, thanks for the note. it’s fixed in the roboDocs fork, update coming soon to Mechanic…

Its indeed similar to a pen. This allows easy subclassing of internal tools by simply adding behaviour to a tool. This tool is subclassing _mouseDragged as it needs the same behaviour but with the shift constrain disabled, as this tool will perform his own shift behaviour.

this is already fixed in the beta and upcoming 1.7 release thanks for reporting!

I don’t know why but the post went to Anonymous. The screenshot is missing so I'm attaching it again. Cheers

Just as I might have expected! Thanks Frederik.
