I super love Krumo/Devel. However, I'm sure I'm missing something obvious, because when I use dsm() and I get my array or object all expandable and awesome, sometimes I have a hard time knowing which array or object it is. At the top, it just says
... (Object) stdClass.
Is there somewhere that it includes the name of the object/array you're exploring? What about on the devel tab of a node?
