The IG External Row View plugin enables you to set up a Row View synchronized to the IG but in an external region. Basically it is a wrapper around the recordView widget, instantiated with the same model and field configuration as the IG, and so makes use of the power of model/view seperation which APEX offers here. This region you can also have as an inline Drawer or Dialog.
Double click in the IG or Row View as to start editing. The Row View fields can be distributed among columns like the above example has 2 columns. The width of the input items can be set to 25%, 50%, 75% or 100%. Also the width of the label part of the fields can be configured.

Below IG has the drawer attached.
