Timeline improvements: new layout modes, span pagination & a mini-timeline

The Timeline is one of your go-to tools for digging into request performance, and we’ve given it a visual overhaul to make even the gnarliest request patterns easier to read.

Two new layout modes

You can now choose how your spans are laid out:

• Condensed (the new default): Reuses lines only within a set threshold and always keeps parent spans above their children. The result is a compact view that still respects chronological order and shows you dependencies at a glance.
• Waterfall: The other end of the spectrum. No lines are reused, so the sequence of events is as clear as it gets — much like the dev tools you already know from your browser.

Prefer the old look? It’s still here as Classic mode, where spans are grouped by summary (handy and compact, though trickier to follow over time). Whichever you pick, we’ll remember your preference per user.

Each mode strikes a different balance between compactness and clarity, so switch freely depending on whether you want the big picture or a step-by-step view.

Span pagination & mini-timeline

With the new modes, it’s not always obvious how often or where a span shows up across a longer request. So when a span appears more than once, the details view now gives you:

• A summary box with the total count and duration
• Pagination to jump between occurrences with a click left or right
• A mini-timeline showing the position and duration of each occurrence, with clickable navigation

We’ve brought this to the Summary and Flamegraph tabs too. Instead of seeing just one span for a selected frame or table entry, you can now page through all of them.
