As explained under → “UI Panels and Windows” it is possible to configure RealFlow's layout to your needs: panels can be added and/or changed in size, and rearranged. All these changes are only temporary though, so they have to be saved:
Layout > Save Layout
The default place for the layout files is located in RealFlow's program directory and specified under → “Preferences”:
Preferences > Layout > Layouts folder
The “Preferences” also provide a “Default Layout” input field where you can determine which file should serve as RealFlow's start-up layout. This UI arrangement will automatically be loaded and applied with each start of RealFlow, but you can switch at any time to any other valid layout file with:
Layout > Load Layout
Layout files from the default folder are added to a drop-down menu under:
Layout > Apply Layout
This way the different layouts can be instantly changed to your current requirements. RealFlow's layout files carry the “LAY” extension and can be opened and read with any ASCII-capable text editor.
