In the Rotate dialog, if "Apply to image" is checked, XnView will rotate as I type. If I type "1.75", it will rotate for "1", then "1." then "1.7" then finally "1.75".
It would be great if rotation happened after some delay (e.g. 0.3s) since the last character typed in the angle edit box.
Whenever rotation angle is changed by the user (by dragging the slider, using spinbuttons, or entering a value), there should be a delay. Currently it is almost impossible to use the slider or spinbuttons if "Apply to image" is active.
