The panels
Every panel Celas Studio has, what each one is for, how to open it, and whether it comes up by default or waits for you to ask for it.
Every panel lives under the Window menu, listed by name. Choosing one toggles it open or closed; none of them carry a keyboard shortcut of their own. Docking, floating and saving your own arrangement as a workspace are covered in Workspaces & panels. This page is the map of what exists.

| Easing | Quick easing presets for the selected keyframes, paired with the Graph Editor | Window ▸ Easing | On | Yes |

"Stays open next launch" only covers whether the panel itself is showing. What a panel remembers inside itself varies: the Cells panel keeps its view settings, for instance, while several others reset their filters and sort order every session. Each panel's own page covers that detail where it matters.
You rarely want all eighteen out at once. Window ▸ Workspace switches between three built-in layouts, General, Animation and Minimal, and lets you save your own; see Workspaces & panels.
