See gary's post about "ViewTest.zip".
After cmd creation, try to reposition the tab to a new horizontal group. Something like this
TrimbleOffice.TheOffice.MainWindow.AppMdiManager.MoveToNewGroup(TrimbleOffice.TheOffice.MainWindow.AppMdiManager.ActiveTab, Infragistics.Win.UltraWinTabbedMdi.MdiTabGroupPosition.Last, Orientation.Horizontal)
This is what it would look like if after executing above.

Let me know if this helps any.

Is there a way to control the size of this? Ideally I would like to have this split the active view similar to the experience we get with the alignment editor? @Bryce Haire

Sure. Just use the cmdData property UIViewForm instead of UIForm in the Setup method. I have attached a simple macro that justs shows TBC help in a view.
Biggest difference is command inherits from a Grid control instead of a StackPanel.

Is it possible for us to create a UI similar to the edit linestring UI?
There are quite a few TMLS that would be better suited for a style similar to this.
