Not sure what you are asking. What exactly is it that you are missing? Muse is not a Layout tool and everything it offers is bound and limited by the requirement to be translated to actual working web pages. A lot of stuff simply cannot exist in Muse simply because it cannot exist in a web browser.
I suggest letting the team know of your feature requests directly using the link below. Remember, however, that objects created using the tools in Muse have to conform to Web standards unlike InDesign that does not have this restriction. Which is why, the number of tools in the two software do not correspond.
