# Split View

> View multiple shards side by side to multitask within a single gem.

Split view lets you divide a gem into side-by-side terminal panes so you can watch multiple shards at once: run a build in one pane while Claude works in another.

## Splitting a gem

Press `Cmd + D` to split the current gem (press it again to collapse the split). crystl adds a new pane next to the active shard with a draggable divider between them.

Each pane is a full shard with its own shell process, working directory, and approval mode. You can run Claude Code in one pane and use the other for manual commands, logs, or a second Claude session.

## Working with panes

- **Focus a pane**: click anywhere inside a pane to make it active
- **Resize panes**: drag the divider between panes to adjust the split
- **Close a pane**: close the shard inside it with `Cmd + W`, and the remaining pane expands to fill the gem

## When to use split view

### Watch logs while Claude works

Split your gem and run `tail -f` on a log file in one pane while Claude iterates on code in the other. You see errors as they happen without switching shards.

### Compare outputs

Run the same command with different arguments in two panes to compare results side by side.

### Monitor a dev server

Keep your dev server visible in one pane while Claude makes changes in the other. See hot reloads as they land.

## Availability

Split view is available in both Free and Guild tiers.
