[FEATURE] New session should push existing top-left session instead of replacing it

Preflight Checklist

• [x] I have searched existing requests and this feature hasn't been requested yet
• [x] This is a single feature request (not multiple features)

Problem Statement

In Claude Desktop, whenever I click "New session", it will always replace the top left session I have running, so then I have to manually reopen and reposition that session.

Proposed Solution

Add an option so that the "New session" button would prepend the new session box to the existing boxes, moving the existing sessions appropriately (would probably require a "max number of rows per column" setting).

Alternative Solutions

New session opens in a popup and popup boxes can be drag-and-dropped into the existing grid.

Priority

Medium - would be very helpful
