There's no "Rotate Snap Image" function

[micheus]

Should it be listed as "Rotate Snap Image" instead of "Rotate Snap Mode"???

Damn copy and past.

If I hit Tab to enter a numeric value > Enter a Value > Reset > Cancel, I am then only able to rotate in one direction.

I needed to understand better the wings_drag module. It's fixed now. [file updated]

Clicking in the Geometry Window gets control back. I need to be more careful when moving the mouse...

You can use the constraint keys for avoid it (SHIFT or ALT).

I see that "Reset" brings back the previous state. Would it be good to also be able to bring back the image's original state?

I can't see this option. The most close of it I found in Proportional Scale->Actual Size ("Reset image to its actual size").
