Vaguely recall that Ethan (others?) wanted to eventually allow slashes in card names?

When is this forecast to happen? Early after 2.0?

Hmm, this isn't on the roadmap and is pretty unlikely, since the long-term plan for names is to replace "+" with "/" as the primary junction of name parts. See DeckoSystems+names

Just renamed this to "replace plusses with slashes" which for many purposes is allowing slashes in card names.

cool, thanks. fwiw, the (forward) slash is THE ONLY character currently formally banned from card names, a la this line from Card::Name: self.banned_array = ['/']. "+" and "*" have special meaning, of course, many characters are absent from urls, and I wouldn't swear on my life that there's no weirdness with other characters, but in terms of formal character bans, this is currently the only one, and the rationale is to preserve the path for the future naming pattern.

Is there value to you in having this Idea card separate from the Blueprint card (DeckoSystems)?

Looking at all the suggestions thus far, I'm starting to love the "+" sign. I love the nature of WAGN as it isn't hierarchical. I fear making the / or \ sign part of the title will make people think too much of file folder hierarchies and their paradigm, which has plagued the computer industry for so long.
