text inside Macro's is changed

We noticed that when putting text in a Macro, some symbols are parsed.
For example double underscore _hello_ is hello with underlining enabled.
** gives bold.
From a user perspective this is an annoying bug: the real content that is typed or pasted is changed.

We would expect to text altering and a WYSIWYG for the text layout, or simply being able to select some layout text and apply the proper Macro.
The described problem occurs in Box, Code and probably most or all other Macro's.

This might also be considered a feature request which would mean that Macro's are somehow integrated in the WYSIWYG.
