Please, please fix this quickly!
I use Evernote business and this is a huge problem for my day-to-day work as I save all my business letters and documents in Evernote.
The major issue is not the annoyance of having to open a .zip-folder and choosing the document, it is that work in progress is no longer saved after opening a .pages-document from Evernote, editing it, and then closing it again. So far I've been able to retrieve the changes from some temporary folder using Pages previous documents menu, but there's a HUGE risk of data loss!
The zipped files are also "lost" in Evernot
