Select, move and resize
Select an object in the plan, 3D view or object list. Use Move/Rotate/Resize and the relevant handles, or enter exact numbers in Properties. Shift-click adds objects to a selection on desktop; drag a selection box where the selection tool is active. The object list’s multiple-selection control also works on touch. Wall artwork alignment/distribution requires compatible works on the same wall side.
Spotlights and room lighting
Add a spotlight, choose wall or ceiling mounting, and adjust position, colour, intensity, beam angle, tilt and direction. The angle dial, ± buttons, keyboard and numeric input offer 1° adjustments. A dial drag commits once at release, so one drag is one undo step. Quality settings may simplify active lights while leaving fixtures visible.
Save and undo
Use Undo/Redo for local editing actions and watch the saving status. Do not close the tab during an upload or before saving succeeds. If another tab edited the same gallery, a conflict protects the newer version; reload/review rather than forcing an overwrite. Keyboard shortcuts are disabled while typing in fields or using dialogs.
