| Android / DuckDuckGo | Works as intended, but moving a dot is difficult. |

| Improvement | Status |
|---|---|
| Add a triangular grid. | Possible. I'll do this if there's enough demand |
| If more grids are added, add snap-to-grid for them. | Harder but possible. I'll do this if there's enough demand |
| Make the line thickness adjustable | Easy to do. |
| Save/restore, so that the user can save an arrangement of fixed points, and maybe other settings, for future use. | I don't think this is possible. Browsers don't allow javascript to affect things like the user's disk. |
Suggestions for other features and enhancements are welcome. Please email them to me at maproom @ gmail dot com
