OK that's mad. How can the user reasonably navigate that many entries in
a single list? Search and pagination are your friends here.
I would tend to agree, however for my Prisjakt application (locates best
price of products) some of my users insisted that the normal searching
(by text or barcode) was not enough - they absolutely wanted the ability
to browse all the products in the tree too. For most of the leaf nodes
the number of items shown in quite reasonable, but in extreme cases
(such as DVD films) it goes beyond 30000.
What I did first of all was allow sorting (by default ranked) and then
only load 20 items at a time - similar to how it works in Android
Market. (I'm pretty sure nobody has ever fetched the full 30000+ list,
but in theory that is likely to cause OOM.)
Since I introduced this, I've had no further insisting users, so either
it is good enough or these particular users have realized that searching
is actually better...
