Steve,

With the new Plant Database dialog being HTML-based, that was one of my big ideas, was to get a little splash of color, a nice indication of adding the plant to the project. Remember the prior version? Just a bit of black text saying "Plant xxx has been added." Boring Alert! lol
To pull off that same with the Detail Library dialog is more challenging. Over time we will be converting more and more dialogs to being HTML-based, to enable all sorts of cool visual effects, as well as an eventual web-only capability -- no reason you can't assemble a project, add plants, assign details, all through the Portal without having to open CAD.
So stay tuned, soon enough!
