Try the same function in Photoshop and you'll see that it is not inaccurate. If you put a layer below other layers, and then work on them, there is no reason why it should suddenly "display" above all the layers, at full opacity. How I am supposed to see behind it? If I wanted it in front of the other layers, then I'd put it above the other layers. It needn't be displayed in front of / above the layers behind / below which I've placed it.

This makes for very inaccurate graphic design, and a lot more inaccurate than what you're describing.

    - Find an image on Google / hard drive.

    - Resize / Rotate and, suddenly, the transparency reverts to
    original state.

    This last step makes no sense.  I changed its transparency for a
    reason and it must stay that way until I say so.

And it does stay that way. Currently, we have an opacity control in the transform dialog. This defaults to 100% IIRC. It only effects the *display* during transform. The opacity setting of the layer is unaffected, it's simply not in operation during that time.

(There are various logical problems with using the layer's opacity during transforms... eg, transforming part of a layer -> overlapping parts are inaccurate, and non-overlapping parts may be inaccurate if the layer has no alpha channel. Same applies to transforming a whole layer.. because the original is not, and must not be, hidden during the transform, inheriting the layer opacity causes problems with the accuracy of the display)
