Option to keep folders and docs arranged by kind or name.
You can sort subdocuments alphabetically by selecting the folder and using Documents>Sort…it’s not automatic, but you could run it whenever you needed to.
…but note that you can’t undo it, (not automatically, that is; of course you can go back and re-sort things). Your original order is not saved anyplace.
ps
But you can sort temporarily using the outliner.
