  • Dark Mode CMD/CONTROL M
  • Zoom In CMD/Control +
  • Zoom Out CMD/Control -
  • Cut CMD/Control X

  • Delete Backspace
  • Select V
  • Pan D
  • Pen P
  • Square U
  • Circle C
  • Text T
  • Eraser X
• Database Persistence

Troubleshooting:

• Switching to localhost: For development purposes, users switch to a backend service hosted on localhost via the menu bar settings.
• Valid Usernames: Must be 8-20 characters long, no _ or . at the beginning or end, no __ or _. or ._ or .. inside. We allow letters, numbers, underscores, and periods.
• Running two instances of the application on the same computer: We use Java's Persistence API to store user credentials. When there are two instances of the app running at the same time, one instance's credentials get overwritten. This causes undefined behaviour with our features. To test multiplayer, please use two or more computers.

Releases

Note for Earlier Versions:

The earlier versions of our app depend on the server to login. However, the server APIs have changed and so has the host. Henceforth you will be unable to login to earlier versions and use the app. In some versions you are able to login, however, the WebSocket APIs are different and as a result the functionality does not work.
