Requesting feature: Viewport Maximize (VPMax)

Hello,

I downloaded BrisCAD to look at how it operated, and 'felt' compared to AutoCAD. One of the first missing 'features' I noticed, that also is not in the e-book about the differences between BrisCAD and AutoCAD, is VPMax/VPMin, and/or the corresponding button. We have been using this to organize our AutoCAD files for some time.
Would it be possible to add this, or a similiar function that allows layout viewport freezing to be applied to full model space, to BrisCAD?
