I'd love to be able to hide photos once I have disabled them. I seem to be disabling ~90% of my photos before building texture most of the time.
Possibly even better would be to dim/grey out disabled photos in the photos pane but leave visible.
It is hard to tell at a glance which photos are disabled just by the little red disabled icon, especially when markers are selected and you also have the marker icon on each photo, disabled or otherwise.
