thanks for contributing.

would the last one not be done better with a dialog box from
a menu command? could be interactive before committing.

let me make clear that the new tool is the general tool for
doing things by _feeling_. there will never be number entry
in this tool, it is optimised for other things. also this
corrective mode I see right now in the new tool is completely
misplaced, 100% against the goals of the tool.

everything you (Liam) need and ask for has its place in the
redesigned precision rotate and perspective tool(s).

I do expect that the redesigned precision tool(s) need to
gain some features for that.
