@syncended/dsh-split-screen

Usage

1. Click Split in the native sidebar footer. The workspace temporarily occupies the center conversation column.
2. Select a pane and use Split vertically or Split horizontally in its header.
3. With the target pane focused, choose a session in the native sidebar. It is added as a tab in that pane; selecting an already-open session focuses its existing tab.
4. Use the pane’s + button to add tabs without changing the sidebar selection. Closing a pane tab never deletes its Harness session.
5. Resize with the divider or drag one pane header onto another to swap complete pane tab stacks.
6. Click Back to Chat or the sidebar Split action again. Harness restores its native conversation surface on the active pane’s session.
