Hi Rich_Art, the way the UI works is that if you click on the center rectangle one time, it will then be the default rectangle tool for the entire rest of that modeling session until you close down MoI.

So changing the default would only actually save you just one single click for an entire program session.

It is possible though to edit the UI and modify the initial default rectangle. To do that go to the \commands folder inside of MoI's main installation folder and find the file Rectangles.xml and open it in a text editor. Then switch the order of the first 2 commands in there, if you put the rectcenter command as the first one in the list it will then be the initial default.
