Thanks Chipp and BurrMan - You both saved me a lot of time.

OK - If anyone simply wants to add four buttons to run Max Smirnov's SubD scripts without making any other UI modifications, I've consolidated and condensed the instructions:

To Install the SubD Scripts by Max Smirnov:
Unzip and copy the following files to the folder: MoI 3.0/commands
_ImportObj.htm
_ImportObj.js
_Subdiv_beta6.htm
_Subdiv_beta.js
_sBridge.htm
_sBridge.js
_sSplit.htm
_sSplit.js
_sScale.htm
_sScale.js

To add Hot Keys (optional):
In MoI go to Options > Shortcut keys and push the "Add" button in there. In the left hand column that says "Key" put in whatever keyboard character you want to use for launching it. Then in the right-hand "Command" column put in the same thing you are currently typing in at the command line.

To add four SubD Icon Buttons (optional):
Make a backup of your MoI folders in case you need to revert back.
Using a text editor, open CommandBar.htm in the MoI 3.0/ui folder.
Find the blue text below. Insert the new white text. Extra spaces are optional and were included for readability (use at least one space character where space is shown).



Download the Icon images from Chipp Walters here: https://altuit.cloud/web/dbpub/MoIGUIdownloads/MODOicons.zip
Select the four icons for the SubD scripts and copy to your MoI 3.0/ui/icons folder

Done!
