Anyone else feel that the functionality around uploading attachments is not particularly intuitive or easy to use? One example - I uploaded the same file twice (a zip file contents of which I updated after uploading it initially and while still writing my post) and I expected it to prompt to replace or not the file of the same name that was already uploaded. But it didn't. I saw both files, same name. Now I couldn't tell which was the more recent, to be sure that's the one that was actually attached to the post. I ended up deleting both, renaming the file locally and uploading that to ensure I had the right file.

Other than that, I like the better post composing features.
