It'd be convenient to be able to edit an existing regex domain instead of having to delete it and rewrite it.
+1 on this. rewriting long regexes from scratch is annoying.
workaround for now is usually copy the regex to a text editor, delete the row, paste a corrected one back in. gravity doesnt care as long as the string is right.
would be nice if the domain list just had an edit pencil like the other bits of the ui.
