Hi Karl, I'm also hoping to release a new beta today hopefully.

re: Construct / Transform tabs, try installing Max's MiniSidepane.js script from here:
http://moi3d.com/forum/index.php?webtag=MOI&msg=8064.8

You can make that script run at MoI startup by putting it in the MoI appdata startup folder. On Windows this is located at %appdata%\moi\startup .

That script will rearrange the side pane like you're asking.
