+1 Along the same lines, I'd love to see some responsive color coding of the text within the macro editor, like in Sublime Text. For example, if you typed in @{selected|token_name}, it could turn blue to show that it is recognized/valid, but if you forgot to add the closing curly brace, it would stay black. This kind of color-coding would really help for troubleshooting macros, letting you spot typos, syntax errors, and other inconsistencies.
