Draw

Reinforce: drag once = one wall segment. After drawing, select it — drag the two white end handles to fine-tune length/angle, drag the "Wall" badge at the midpoint to move the whole segment, and set the panel count (Wall×N) in the right panel.
Opening: pick one of vault/walkthrough/gunfight/foot/floor, click to place — picked the wrong type? select it and change it after.
Text label: click to place, edit the text on the right to name a room.
Placement: pick an operator on the right, then a gadget, click to place — drag to set facing.
Selecting any marker shows handles: white = resize, blue = rotate facing/vision cone. Placements get an extra orange handle to rotate the icon itself, independent of facing. Handles auto-fade after 3s idle — click the icon or drag a handle to bring them back.
Draw: pen/highlighter — hold and drag to freehand; line/arrow/rectangle/ellipse — press, drag, release; eraser — click a stroke to delete it. Everything supports Ctrl+Z.
In any tool, pointing at an existing marker always selects/drags it instead of stacking a duplicate — click empty space to create a new one.
Shortcuts: Esc / right-click cancels and returns to Select · Delete removes · Ctrl+Z undoes
