The panels prevent me from looking at my image
Panels may prevent the review of the image in the main window. You can mask them using the Tab key.
Moreover, you can activate full-screen mode, and use it not only for editing but also for a preview. Use the F11 key to switch between full-screen and normal mode.
You can customize the interface by altering settings in the Image Windows tab-Appearance going through Edit menu-Preferences. Here you can specify the appearance of the full-screen mode as well as the normal one.
Changed settings will take effect only after restarting the program.
