I have updated the new component to be totally local. Type any velthuis mixed into your post and it will make a copy below. You will need to delete the original until I figure that out. Try it out!
You will see a button called en.Pāḷi in the composer window, type velthuis and click and see what happens. 
Here is a sample after pressing the paa.li button:
eva.m me sutta.m--------------------new text--------------------
Here is a sample after pressing the pāḷi button:
evaṃ me suttaṃ
