The filtering capability is great - well, almost.

The left side of the frame shows the different filters, where the right side shows the list of items for that filter. Clicking on an item takes you where you want to do, but there's no way to 'get back' to the exact location in the filter list where you left off. I've been tracing through a filter list to make sure all the item(s) are done, but I have to keep clicking on the filter list in the left, then to the right page, then scroll down, etc.

It would be nice to split the left part of the frame into two sections, similar to the project explorer - on the far left, a list of the filters, the 'middle' with the items, and the right the last selected item. This way you can scan through the items in the filter and see the current item without have to 'go back and find' where you left off.
