I thought I'd use this as a small project after a long break to take a first step back into Inkscape development (see bzr rev. #9976). You can now cycle through items that are stacked on top of each other by using Alt+mouse wheel scroll (use Shift+Alt to add to selection). I hope it is intuitive enough but let me know of any problems or suggestions you might have. At the moment, groups are not honoured (i.e., only individual items within groups are selected). Should this be added (perhaps using Ctrl as the keyboard modifier)? Could there be problems with nested groups, though?
Inkscape 0.48+devel r9976 on OS X 10.5.8:
Great feature :) - haven't tested in depth though for further feedback because Inkscape immediately crashes/hangs if the mouse pointer is moved just a little bit while 'Alt' is still pressed and one object is selected while the other ones stacked below the pointer area are rendered with reduced opacity.
Reproducible with default preferences, SVG file used for testing attached (objects on three layers), as well as backtrace.
