I never really got out of the digitizer interface from DOS days when AutoCAD use to "sing"
This "digitizer" interface I use is fast, full of embedded LISP code that out performs most pull-down, slide-side-ways, scroll down to find the command type draughting... it utilizes DOSLIB, OPENDCL and iDwgTAB to make draughting fun again... but then, I'm an old bugger, set in my ways.
Is the right side of your screen the "iDwgTAB" or something else? I think I might have to try that out.
Yes,
The Left-hand side with layer disciplines is written with OpenDCL, has "slide-out" menus for sub-layer selection. It switches to the selected layer if it exists or changes gripped entities to the selected layer or creates the layer if it doesn't exist and can change gripped entities to a new selected layer. This function was created out of a strict need for layer management. That way only layers that are required exist in the drawing file.
The middle section is using AutoCAD's standard toolbar functionally, but also gets increased speed with "QuikPik" (

The Right-hand side is "iDwgTab" and is a must for visual selection and changing to drawings quickly.
All sections are movable and can be repositioned programmatically, so there is no need to stay with the screen layout as shown, though most monitors have resolutions that support the "A" series paper sizes and still allow these customization areas sufficient screen real-estate.
