Hide the stages and tools you don't use from Studio's own sidebar — this only changes what you SEE. Anything already switched on keeps working exactly as before; hiding it just gets it out of your way. Turn a stage or a tool back on any time and every setting is still there, untouched.
Download your saved looks and this Studio layout as a .micro setup file — no photos, just your configuration. Keep a copy, or import it on another computer to carry your presets across. Importing replaces your current presets and layout with the file's.
Everything the export above carries, listed. Tool presets are the ones you save from a tool's own Presets row in Studio; full looks are whole-recipe saves from the toolbar's Save menu. Deleting one here removes it from this browser only — an exported .micro still has it.
Photos you import are cached on-device in this browser (IndexedDB) so the Gallery and filmstrip survive a reload or crash. Clearing them frees that space and empties the Gallery and the crash-recovery snapshot. Your saved presets and this Studio layout are kept — they live in a separate store and are never touched.
