<caolan> noel_grandin, wrt the accessibility labelled-by and label-for. If the label really is a GtkLabel then setting its mnemonic target (in glade, general tab, and use underline and select a target) is the most straight forward thing to do and implies those a11y relations
<caolan> the painful manual a11y labelled-by/label-for are typically for using something weird, like a checkbutton, as a label for something
