1 Editor Basics

Interface Layout

The management page works in phone browsers — columns, numbers and the detail panel reflow for narrow screens. Phones suit quick number edits, marking taken and switching Wi-Fi; fine layout work is better on a computer with steadier dragging and zooming.

Top Bar Buttons

"Render preview" checks the finished look without pushing to the screen. Daily editing already goes up automatically; use "Push to Screen" only when the screen seems out of sync.

The top bar also has a "Developer" button — a supplier maintenance entry. Do not click it in daily use; a power cycle restores things if touched by accident.

Canvas Operations

• Select: click a column or number; its properties appear on the right.
• Deselect: click empty canvas; the panel returns to "Overall Settings".
• Move a number: drag it; releasing auto-saves and pushes.
• Move a column: drag its empty area; locked columns cannot be dragged.
• Resize a column: drag the bottom-right handle to change width and height.
• Zoom the view: use "−", "+" and "Fit"; zooming affects the editing view only, never the screen.
• Grid: show/hide the editing grid as an alignment reference.

Auto-Save and Push

There is no "save" button. Every content change is written to the device automatically and pushed after a brief merge:

• inputs commit once typing stops;
• consecutive edits merge to avoid screen churn;
• on a normal network, screen updates take about 0.2~0.3 seconds;
• changes committed before closing the page are already saved — the browser need not stay open.

If the network drops or an operation errors, the interface reports the failure — the change may not be saved, so redo it once the network recovers.

Undo, Redo and Shortcuts

Undo: Ctrl+Z; redo: Ctrl+Y or Ctrl+Shift+Z.

Undo covers adding, deleting, editing, dragging, reordering, cross-column moves, marking taken, changing backgrounds and clearing. The undo history lives in the current browser page — refreshing or closing clears it. Inside an input box, Ctrl+Z undoes text first and does not reach the canvas.

Note: after a background switch succeeds, the device cleans the old file. Undoing "change background" may restore only the layout record while the image is gone — keep local copies of important backgrounds.
