About Collab Doodle
Everyone connected to a channel draws on the same canvas at once. There are three channels, main, sketch and test, with canvases up to 1920x1080. The top screen shows a minimap with who's there, the bottom screen is where you draw.
Brushes come in circle, square, dither, spray, diamond, cross and eraser shapes, sized from 1 to 12. Colours can be typed in as hex codes, and you get eight favourite swatches. Zoom goes from half size to 4x. There are control layouts for right-handed and left-handed stylus use, or you can set your own. Settings live in /3ds/CollabDoodle/settings.ini. The app checks for its own updates.

Collab Doodle 1.6.2 — Feather, New Brushes & Canvas Changes
Version 1.6.2 makes drawing feel smoother, expands the tool palette, and
polishes touch navigation throughout the 3DS client.
What's new
- Added a persistent Feather toggle for soft brush edges, including Dither and Spray.
- Added Diamond, Cross, and Spray tools alongside Circle, Square, Dither, and Eraser.
- Tuned low fractional brush sizes for more continuous strokes and opened up Dither and Spray spacing.
- Added a shared
1.0–12.0size slider with0.1precision for every tool. - Improved color-picker edge accuracy so pure white, black, and saturated colors are easier to select.
- Added support for per-channel canvas sizes up to
1920x1080, with dimensions shown before switching. - Added touch Back controls across menus. Refreshing a canvas now preserves its pan and zoom.
- Improved Support and staff workflows with dated timestamps, responsive loading notices, and Send/Edit/Cancel actions when reporting a user.
- Kept the drawing palette fully touch controlled; your configured Tools button opens and closes it.
Upgrade notes
- Existing identity, controls, favorite colors, brush settings, and other device settings are preserved.
- Older released clients enter the updater before normal canvas use.
