Maybe this would be better applied to sticky block management? Since this task relates directly to setting stickies and avoiding duplicates, it seems a logical place. 'Course, this is probably what you already had in mind *lol*
It would also be the natural place to address the loophole I mentioned in my last post (that 'prevent multiple instances' is ignored by My Moodle page stickies). This would be a useful function - if it worked with the My page - but it would be significantly more useful if it could be configured in other contexts (as proposed on Development:Navigation Blocks/pagelib).... But I guess I should post comments about that on the other forum
