the pop-up menus for lines, materials, fills, etc, is completely illogical, i.e. it is organized neither by attribute # nor alphabet.

Lines and Fills are organized alphabetically by type (first, simple line types/fills alphabetically, followed by symbol line types/fills alphabetically), this you cannot change (unless you want to force a specific order by renaming all of these attributes).

Because of the havoc it can wreak with Library Objects (and the fact that AC recognized most Attributes by their Index Number, not their name), I don't recommend messing with existing Attributes unless you know what you are doing. Search the Forum for other posts regarding this matter.
