Thanks for replying to my message.
I think the .pages issue might be my computer not showing file extensions by default, because it seems to treat files with and without the extension as the same file.
I will sync the SME app before each iWork use. Usually if I want to edit a document on iPad, it is after working on it on my notebook. It only takes a few seconds to do I suppose and it should tie me over until iCloud. It's better than Dropdavs $5 per month fee :3
EDIT: Actually there was just one more question. I noticed that in one of my Dropbox folders (one that wasn't shared) an image file named "angle1" appeared and then disappeared a minute later. I couldn't really think of how this might have happened. Is "angel1" a test file used by SME when testing customer Dropboxes? Because no one else has access to that Dropbox folder.
