You don’t have to keep them all open all the time!
Each Lightroom module has a range of panels, such as the Library module’s Keywording panel .
Some panels may be more useful to you than others, so you can minimise the ones you want to hide by clicking these icons . The hidden panels will reappear when you move the cursor near the sides (or top and bottom) of the screen. If you want less clutter, get rid of displays that you don’t use by right-clicking a panel to activate a context-sensitive pop-up menu.
Clear any panels  that you don’t often use to make more space. The Solo Mode  means you only have one panel open at a time.
