In the version of Windows Live Photo Gallery I have on a Windows 7 machine, the program shows Date Taken, People Tags and Descriptive Tags on the left side under the included folders.  To filter by tag, all I had to do was select the tag from that list on the left.  In the version on my Windows 8 box, those are gone.  In order to filter by tag, I have to select the Find tab tab, then select Tags, then scroll down through the tags until I find the one I want.  Is there any way to get that list of tags on the left side like in the previous version?

Second, why are the people tags separate from the descriptive tags?  There are programs that will recognize the descriptive tags, but not the people tags.  Is there any way to convert the people tags to descriptive tags so they work the same way?
