I recently evaluated mockup apps (from Balsamiq to Moqups to Mockingbird to Axure) for a new project of ours, and nothing I found gave me what I needed—which was the ability to mock up interactivity in a predictable, easy, and non-tedious way.

I made my own library instead to simply control state in an HTML page using simple, logical class names and IDs. This, combined with Bootstrap, made an HTML mockup a very fast and easy way to do exactly what we needed.

Is there some new feature in Moqups that helps with interactive state such as this? Or do you have any suggestions on what the "best practice" for interactive UI mockups should be?

Or is this something people don't usually do? Is it seen as "too realistic" or unuseful? So far we've found the interactive mockup invaluable in honing generic UIs and determining which direction to go, so I can't believe it's so difficult in most tools to control and easily switch component states.
