Thanks again for all of your comments! We have rewritten [Trixi.jl](https://github.com/trixi-framework/Trixi.jl) completely to make it more modular and Julian - we made the transition from “Trixi as a monolith” to “Trixi as a library” (search for PRs/commits/issues mentioning “Taal” in our [repo](https://github.com/trixi-framework/Trixi.jl)). In particular, we got rid of TOML parameter files to set up simulations and replaced them by pure Julia code.  
See our [new announcement](https://discourse.julialang.org/t/ann-trixi-jl-v0-3-sciml-integration-and-a-new-modular-approach-for-easy-extension/50419) for further details.
