Hi Ced - MoI's UI was specifically designed not to have floating toolbars, because I don't like how they obscure your working area. Trying to keep things uncluttered has been a big goal. It's pretty much a fundamental idea in MoI's UI to have a reserved area at the side of the screen where most UI can be shown, so stuff like you're showing there will be kind of difficult to set up since it hasn't received any attention in the UI engine design.

It is possible to create dialogs for floating windows though, see here for an example of how to make the side pane appear in a dialog:

Your "inner shadow" part would be done with a CSS inset box-shadow, but unfortunately the version of QtWebKit that MoI v3 uses does not support blur on shadows. It seems that this has been fixed in the newer version of QtWebKit that MoI v4 will use, so in v4 it will be possible to do something like style="box-shadow: inset 0 0 20px #000000;" for an effect like that but it won't work in the current MoI v3.
