Summary:
When possible, render application transactions via Ajax. Instead of reloading the page when the response returns, append new transactions to the transaction view.
Scroll the window to the new transactions, animate them in, and clear the form to make this interaction feel reasonable.
When editing transactions, fade them in but do not scroll to them (i.e., don't disrupt the user's position).
Test Plan: Edited and appended transactions via Ajax. Observed fade in animations and scroll behavior. Clicked anchors to verify proper anchor accounting.
