Dan,
Brett posted a new install in the Announcements and updates thread. Have a look at it. I think you will like it.
There is now a choice of editors for the DROs.
1. In place (with the changes you wanted).
2. Basic keypad.
3. Extended Keypad (math funcs).
4. Read only.
You will have to edit the screen and change the DRO's "Editor" property to get the Keypads. The in place editor is the default. Once you change a DRO to the Keypad type editor, you will then have to enable "Auto Calc" (like Mach 3) in the Operator menu. The setting is persistent.
