Hey,
currently I am only interested in fixing bugs. I wanted to work on higher resolutions and naming but I am currently working on a project for study. I don´t think I will add new features till Christmas.
If you want to contribute or edit the container to your needs, you can download the project on Github here. Basically you´ll need to edit the files accordingly to your needs and then build the container with docker (there are plenty of tutorials on Youtube). If your build then is without issues you can create a pull request on github, I will test it, and then merge it to the main branch. This would make it available to everyone via an update.
