## Platform-Aware View Metrics

When you open the detail panel for a View, the metric cards on the **Performance** tab adapt to the View's platform, so you always see the metrics that platform actually exposes.

| Platform                   | Performance Metric Cards                                              |
| -------------------------- | --------------------------------------------------------------------- |
| **Browser (Web)**          | `LCP`, `FCP`, `INP`, `CLS`                                            |
| **Native (Android / iOS)** | `refresh_rate`, `cpu_ticks`, `memory`                                 |
| **WeChat Mini Program**    | `first_render`, `lcp`, `fcp`, `onload_to_onshow`, `onshow_to_onready` |

<Note>
  The platform is determined by the View event's own `source` field — no manual switching needed. For Mini Programs, `onload_to_onshow` and `onshow_to_onready` cover the two segments of the page lifecycle and help diagnose slow cold starts.
</Note>

The EventTable column picker also supports the following Mini Program-only fields as queryable columns: `view_first_render`, `view_onload_to_onshow`, `view_onshow_to_onready`.

## Saved Views

The saved views feature allows you to save your current query state as a reusable view for quickly switching between different analysis scenarios. Each account can create up to **20** saved views, and views are only visible to you.

### What a View Saves

Each saved view contains the following information:

| Saved Item          | Description                                                                      |
| ------------------- | -------------------------------------------------------------------------------- |
| **Time Range**      | The currently selected time filter                                               |
| **Query Type**      | The currently selected event type (e.g., Sessions, Views, Actions, Errors, etc.) |
| **Query Statement** | The DQL filter conditions in the search bar                                      |
| **Custom Columns**  | The column configuration of the data table                                       |

### View Operations

<Tabs>
  <Tab title="Create View">
    Click the view menu at the top of the Explorer, select "Save as New View", enter a view name, and confirm. View names must be unique.
  </Tab>

  <Tab title="Switch View">
    Click the view menu and select the target view from the list. After switching, the Explorer automatically restores the saved time range, query type, query statement, and column configuration.
  </Tab>

  <Tab title="Edit View">
    In the view list, click the action menu on the right side of the target view and select "Edit View" to modify the view name. If you have modified the current view's query conditions, you can also use "Save Changes" to update the view with the latest state.
  </Tab>

  <Tab title="Delete View">
    Select "Delete View" from the view list or action menu and confirm. After deleting the currently active view, the Explorer automatically switches back to the default view.
  </Tab>

  <Tab title="Copy Shareable Link">
    In the view list, click the action menu on the right side of the target view and select "Copy Link" to get a shareable link for that view. Share the link with team members so they can open the same query view directly.
  </Tab>

  <Tab title="Reset to Default View">
    Select "Switch to Default View" from the action menu to clear all filter conditions and restore the Explorer to its initial state.
  </Tab>
</Tabs>
