Developer Notes

Customizing Screen Marker Positions - #1953

Using custom marker positions for the screen marker calibration choreography might be a common use case. Previously this was not easy to achieve with a custom plugin, as the relevant function was a private method. We have now made it public so that you can more easily implement custom calibration choreographies.

Black Formatting Checks on Travis - #1956

We are internally using Black as automatic Python formatter for our codebase. This helps us ensure that PRs only contain relevant changes and no formatting/whitespace changes. To enforce this more strictly, we added a black formatting check to our Travis integration, which will run on all commits and PRs. Please make sure to format your code with black before submitting a PR to ensure that all Travis checks pass.
