The new AI experience is great to use, especially when working with two windows side by side. It would be helpful if the AI panel could be resized by dragging the divider, rather than being limited to the current fixed layouts (small side panel or half the screen).
Being able to adjust the split (for example, 2/3 and 1/3, or any preferred width) would let users tailor the workspace to the task at hand. This would make it easier to review larger documents while still keeping AI readily accessible, creating a more flexible and productive workflow.
