How to change panel sizes in the workspace

[F�bio Paschoal]

When I open Lightroom, the panels with the image are small and the side panels, with the editing options, are large. How to make the image bigger and the other panels smaller? (does not work trying to decrease with the mouse arrow)

If you position the mouse cursor exactly on the border line between side panels and main editing window- a double-ended arrow cursor should allow you to drag the panel border to narrow them down.

Not forgetting that you have options to show/hide all panels by a [Right-Click] on the triangle at the very edge of the LrC UI-

And Function Keys F5 F6 F7 F8 are also quick ways to Hide/Show panels.
