## **Description**

[![Open in GitHub
Codespaces](https://github.com/codespaces/badge.svg)](https://codespaces.new/MetaMask/metamask-extension/pull/28086?quickstart=1)

### Motivation

- Creating a Sentry custom span that would capture this performance
issue:
  - #27500
- It was determined that the issue is not captured by the existing "UI
Startup" custom span
(MetaMask/MetaMask-planning#3398).

### Approach

I've decided to widen the scope of this ticket so that it covers
performance issues with all accounts in general (not just those created
with the `account-watcher` snap).

To this end, I've defined three new custom spans: 

- `'Account Overview - Asset List Tab'`
- `'Account Overview - Nfts Tab'`
- `'Account Overview - Activity Tab'`

#### Behavior

- **Triggers** a) when an account list item is clicked in the account
list menu component, or b) when an account overview tab (e.g. "Tokens",
"NFTs", "Activity") is clicked, or c) (Only for `"Account Overview -
Asset List Tab"`) the "Import" button in the detected token selection
popover is clicked.
- **Terminates** when one of the following happens (race):
  - A different account is clicked in the account list menu.
  - An account overview tab is clicked.
- The newly selected tab component finishes loading -- including its
resources.
- If there is no data to display, the loading spinner/message
disappears, and the appropriate filler content renders.

#### Helpers

- Added selector for the `defaultHomeActiveTabName` property of the
`metamask` slice.
- Added enum `AccountOverviewTabKey` and objects
`ACCOUNT_OVERVIEW_TAB_KEY_TO_METAMETRICS_EVENT_NAME_MAP`,
`ACCOUNT_OVERVIEW_TAB_KEY_TO_TRACE_NAME_MAP`.

### Results

- The custom spans function as expected.
- The spans successfully distinguish periods of inactivity with loading
time.
- The spans continue to capture delays while the UI toggles between
accounts and account overview tabs.

- The custom spans capture the performance issues that motivated this
ticket
  
- #27500 (see 1.46m
long Nfts Tab span and 5.49s Asset List Tab span)

- #28130 (see 1.28m
long Nfts Tab span and Error message: "Cannot destructure property
'imageOriginal' ...")

## **Related issues**

- Closes MetaMask/MetaMask-planning#3516

## **Manual testing steps**

1. Click one or more of the account overview tabs ("Tokens", "NFTs",
"Activity").
2. Click Account Menu
3. Switch account and repeat.
  - Add accounts as necessary.
- For load testing, add whale account(s) using the experimental "Watch
Account" feature.
