It would be useful to have a gumball mode for “Align to View”. I have a script for this which gives me a good starting point, I usually only need to adjust the rotation once from there instead of three times if starting from aligned to c-plane, but the script needs to be summoned with every new selection, and it forces a view reset which is jarring. (Not a new request but would be nice to see implemented in V6, from Dec 14 Rhino 6 Wishlist - Gumball “Align to View” Mode)
For consistency’s sake, when working in planar views I wish the gumball numeric input windows for rotation were the same as the standard rotation command, by which I mean relative to the view positive numbers are always counter-clockwise and negative always clockwise. As is I always have to check the display to see which way the arrows point before I input the number. (Also not a new problem Does Rotate in Gumball work backwards?) I suppose there is a logic for this depending on whether the axis arrow is pointing toward the view or away, but from a user perspective it just feels like an inconsistent and unhelpful UI.
