While this pack is affected by this deprecation, it needs to be fixed in the space-pen package. But since that has been deprecated by GitHub, the second best choice would be reporting this issue in the space-pen-plus. Once a fix is available, replacing the dependency on that package should be trivial.

The alternative would be rewriting the UI, which probably won't happen anytime soon (if at all).
