Here’s a nifty setting to close up panels in your Lightroom modules that you’re not currently using without having to scroll.
Right-click on one of the panel headings in the Develop module (Basic, Tone Curve, etc.). Scan your eyes towards the bottom of the opened selection menu. Click the “Solo Mode” option to select it. Now when toggling to open another panel, the last opened panel you’ve just left will automatically close. Love it!
From that same selection menu you can hide/turn off panels that you may not regularly use (like Lens Correction or Camera Calibration, for example). Just don’t forget that you turned those panels off in case you ever need to use it for your image adjustments.
Solo Mode is also available in the other Lightroom modules.
