This is a suggestion for improving viewing of Amplifier data: allow filtering of results based on callgraph structure. Here's the use case: I only case about the performance of a specific function and its descendants. I cannot reliably tell when the function starts and stops so I can't use pause|continue feature. Instead, I run full analysis, find the top-level function I care about, right-click on its name and select "Concentrate on subtree". Amplifier would remove all functions that are not called, directly or indirectly, from the top-level function I selected and re-calculate the %s for each remaining function. This is a very handy feature present in another commercial run-time analysis tool.
