Looks guide good! I added some minor comments

Visually speaking, what if we make the components closer to what's on the rest of the page?
Like the buttons, the input box etc. Otherwise it feels a little too...disconnected.

Looks good, the only thing I noticed is that for diff it uses "flamegraph" as the default name

But merging this anyway.
