This is an idea for @vimala and @blake to consider.
It’s a simple thing, but I notice that our normal links on (sub)division and details pages don’t have title attributes. May I suggest that we add a title that gives the “expanded” form of the ID, as given in uid_expansion.csv.
Where currently we have, say:
<a href="/pi/mn1">MN 1</a>
Which displays as MN 1
we’d have
<a href="/pi/mn1" title="Majjhima Nikāya 1">MN 1</a>
Which displays as MN 1
This would help newcomers learn the meaning of the IDs.
