You should at minimum be able to filter Landing pages by Page Name, not just by Page Title. I would like to create a different Landing Page property that I could use as a tag-like field/property so as to group landing pages.
Or I'd like to be able to use the Folders system for Landing Pages to filter against. There's no good way to get at Page Views of many Landing Pages without manually adding and maintaining a report with landing pages. Or by using some publicly viewable Page Title tag to filter against. Not even Campaigns can be used to filter Landing Pages
