Maybe have Detect Life built in only while sneaking? That way it wouldn't be obtrusive while you're walking around talking to people and stuff.

Are you wearing the Ebony Mail? "Wearing the armor also counts as an unsheathed magically charged hand, as guards will comment as though the player were walking around with spells at the ready." http://elderscrolls.wikia.com/wiki/Ebony_Mail

SkyUI is still a work in progress. There's a good chance crafting menus will be added down the line, but that's just conjecture afaik.
