Everytime the twitter feed refreshes on feed screen, only last few tweets are loaded ~50 at max. Tweeter allows upto last 200 tweets to be retrieved in one request. Can we achieve that in feed screen?

Isnt the maximum 500?

Settings>Applications>Feeds> Number of items

wish there was a way to update once we scroll down instead of having a fixed number much like twitter website

That's number of feed items to keep. Its a separate thing, related to the feeds app.

i'm looking for twitter feed on homescreen
