Caydiem has confirmed that we won't be seeing 1.7 very soon. Which is too bad, since I have some updated features for the SimpleInventory AddOn which I'm planning on releasing when 1.7 goes live.
First off, I've added a new "Sort by bag" checkbox for the bank and main inventories. When this is selected, the simple inventory display lists your bags and displays the items located in each bag. You can move items between bags in this way.
Secondly, I've added a Lua function that allows you to get the count of the number of items of a given name you currently have. This can be used in macros via the /script command.
