Am I missing something here or is there no method to return a list of the keys added to the dictionary?
No your right it is not there. I guess we never needed it internally in our plugins. Nor did user request it. I agree it should be there though. I will look into it.
Would not so difficult to build it yourself , do I miss something here ?
Of course, but it is an obvious omission, so I was just wondering if I somehow had missed the method name somehow.
