Diagramming & Text

The editor was limited to block art — no way to draw connections, label things, or type text. To be useful for diagrams (boxes, flowcharts, labeled icons), it needed line-drawing primitives, a text input tool, and selection/copy/paste for repositioning.

Add diagramming character palette, a text typing tool, canvas nudge controls, and selection-based copy/paste.

• Box-drawing character palette (lines, heavy, double, rounded, dashed, arrows)
• Text tool with keyboard input and cursor
• Canvas nudge (shift content up/down/left/right)
• Select tool with drag-to-select, auto-copy, click-to-paste

• Diagramming palette — 7 new character groups: lines (light), heavy, double, rounded corners, dashed, arrows, diagonals
• Text tool — click to place blinking cursor, type characters left-to-right in active color, arrow keys to move, Backspace to delete, Enter for next row, Escape to exit. Supports clipboard paste for multi-char text.
• Palette auto-switches to paint — selecting any character in the palette switches the active tool to paint
• Nudge controls — 4 arrow buttons beneath size sliders to shift entire canvas content by one cell in any direction
• Select tool — drag to highlight a rectangular region, auto-copies on mouse release, next click pastes at that position (empty cells are skipped to preserve background). Cut mode checkbox clears the source region on paste.
• Design system colors — color palette expanded from 6 swatches to full Grape/Leaf/Grey ramps plus semantic colors (error, warning, blue)
• Preview font — switched to Menlo with emoji fallback stack, tuned line-height (1.03)

Editor now supports diagramming workflows: draw boxes with line characters, label with the text tool, reposition content with nudge or select/copy/paste (with cut). The tool type expanded from 3 to 5 (paint, recolor, text, select, erase). Color palette aligned to the Qpoint design system.
