In uncovering our top offenders in lack of code coverage we are missing coverage in: [src/profile-logic/profile-data.js](https://codecov.io/gh/devtools-html/perf.html/src/dde68013d994ec113c7513f85f2b0eadee9af2cf/src/profile-logic/profile-data.js) We need to test: * [ ] `findBestAncestorCallNode` ┆Issue is synchronized with this [Jira...

While looking for top file offenders for code coverage, this one stands out. We have no coverage for GC marker processing. https://codecov.io/gh/devtools-html/perf.html/src/dde68013d994ec113c7513f85f2b0eadee9af2cf/src/profile-logic/process-profile.js#L494 ┆Issue is synchronized with this [Jira Task](https://mozilla-hub.atlassian.net/browse/FP-690)

Provide a way to collapse non-branching call nodes in call tree

 Looking at a call tree like this is kind of unhelpful, as it doesn't show anything pertinent that is going on. It would be useful to be able to...

With PR #709 the types needed to change in `src/types/indexeddb.js`. We should investigate what's going on here. See https://github.com/devtools-html/perf.html/pull/709#discussion_r161786815 ┆Issue is synchronized with this [Jira Task](https://mozilla-hub.atlassian.net/browse/FP-688)

We should have some nice documentation about what is going on in #709 ┆Issue is synchronized with this [Jira Task](https://mozilla-hub.atlassian.net/browse/FP-687)

The Viewport component is slow

2

I believe the fix here is to unhook the Viewport from dispatching actions. We should attach an event emitter to the store that operates independently of the actions. The mouse...

Host profiling examples

We should host the examples or expose them better. I also have a few from presentations I need to merge in. ┆Issue is synchronized with this [Jira Task](https://mozilla-hub.atlassian.net/browse/FP-682)

Audit and change HTML tags to be semantic according to its use

e.g. use real title like h1, h2. ┆Issue is synchronized with this [Jira Task](https://mozilla-hub.atlassian.net/browse/FP-680)

Add keyboard shortcuts across the tool

This should be broken out into separate issues on each tab with an agreed upon set of keys to use. ┆Issue is synchronized with this [Jira Task](https://mozilla-hub.atlassian.net/browse/FP-679)

De-duplicate performance.mark and performance.measure
