Under your MoI3.0 command directory \ui \customui,
item 80 ExtScripts.htm refers to \mods\ExtScripts.menu.htm,
which excludes the "stock" MoI3 commands, which MoI already has
standard selection buttons for. So there is no need to have them cluttering up
the custom screen list of "added on" "non-stock" scripts.

Do NOT do the next two sentences:
To disable, make it -80ExtScripts.htm, with the minus sign.
And enable full version by removing the minus sign in front of
81 ExtScriptsFull.htm, which references \mods\ExtScriptsFull.menu.htm. (Do not do this:-)

Ext. scripts typically have an underscore prefix: _SomeScript.js, AND _SomeScript.htm,
but if they do not, and they are not excluded, they may occur at the END of the scripts which are preceeded by an underline _.

Maybe your additions are at the end, or do not have both .js and .htm preceded by a underscore _?
