Muse is great for putting up content while traveling, especially with Lightroom and Photoshop mobile apps getting more robust. I can keep friends and family up to date without have to deal with Muse quirkiness on the road.

I would like to be able to open a page in the same (_self) window, and have a "back" button option to return to initial page, rather than forcing every link to open in a new window. If you create a "home" page with links to other pages and links back to the home page, you end up with a lot of windows. Yes, you can close the new window, but that's not natural browsing behavior. See here: https://spark.adobe.com/page/S6x8HOu6BaeVm/ for an example of how an index page of sorts can be made, but creating a kind of multi-page website that behaves normally doesn't quite work.

Incidentally, for somebody looking to put Spark content into his own domain, there is a plug-in available for Muse which does a pretty good job of inserting Spark Page content into a Muse site.
