On the Edit Person screen, the Living flag is on the far right hand of the screen, below Sex and Suffix.
I think this is a case were the usability of RM would be improved and the clickiness would be reduced if a little bit more information were displayed in the big panel in the upper part of the screen that has the person's name, birth info, marriage info, and death info. The right hand side of this panel is pretty much empty. I wish the empty space included the person's sex, living flag, and relationship. The relationship is already on the screen, but it's in a tiny font in the far bottom left corner of the screen and a lot of iusers don 't even notice that it's there. I think the relationship should be in the top right corner of the screen instead, and in a slightly bigger font.
And while we are wishing happy thoughts, if those items were in the top right corner of the screen in the unused space that's already there, why not make the sex and the living flag editable without having to go into the Edit Person screen. If the Living flag is on,click it and it turns off. If the living flag is off, click it and it turns on. If the sex is male, click it and it becomes female. If the sex is female, click it it becomes unknown. If the sex is unknown, click it and it becomes male. No drop down boxes would be required. Drop down boxes are sometimes necessary, but drop down boxes = clickiness.
