[UX] [multilingual] Translated blocks are too hard to use

My non-technical co-worker seems to find translated blocks difficult to work with, he would continually follow the "Configure block" contextual link to translate it, but then end up editing the source translation.

I would suggest a contextual link to translate the content and/or that the block configuration popup be more obvious about the content being the source translation (although my co-worker probably wouldn't have much of an idea what source translation means). Perhaps disabling (or with an option to disable) editing the source content directly from the configuration popup would produce fewer mistakes.

Discuss. :-)

As a stop-gap I wrote a small module that adds the contextual link.
