The GUI should be consistant in it's action. Scroll-wheel zooming in and out is a great feature for the most part. The point at which the behaviour changes and it jumps to one side is mentally disrouting and breaks work flow. It seems that there is an implicit assumption in the current behaviour that if the image can fit into the display window it absolutely must be centred. It seems that this assumption needs to be re-examined. Is this always the best behaviour? On opening an image it would seem a logical choice but on zooming out I would maintain that continuity of the mental focal point is the most important for usability and workflow. In this context whether the user wishes to ALSO centre the image in the window is a secondary and largely separate issue. This can be achieved by a shrink wrap for example. I'm glad this subject has come up because this is a constant annoyance when working close in on images. The initial zoom-in is generally a series of zoom-drag-zoom-drag.... operations. There is no reason why subsequently re-zooming to the same work area should be equally laborious. /gg _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
