I've been trying this beta feature for a while now on the English Wikipedia, and I like it. There's one feature that I hope can be reworked. Currently, posting a comment will insert the user's signature at the very end, which is useful for those of us who forget. That being said, there are times where having the signature at the very end isn't wanted, such as using a {{reftalk}} template at the very end. Could this be overridden by inserting four tildes in the comment and have the signature render there and not at the end?
ETA: I also notice that there are some issues with certain templates that has their transclusion break with indenting, like reftalk. Perhaps an option to remove indents could be considered?
