Persistency sounds good to me, however I don't see much reason in moving modal dialogs on the screen except 'just for fun'. Resizing dialogs assumes that they all have scrollable and resizable content. Layout of the content has been carefully designed and will very likely 'break' when dialog is resized unless content is packed in a scrollable widget. In fact you can try this with several desktop apps and see how they break. > >>> they'd not stay put next time, because maemo doesn't have persistent >>> state. >> >> Could you give an example of this problem? > > Not for dialogs/notifications, as they're not adjustable.
