Todo list for DGMulti solvers

I added > Add StartUpDG.jl as direct dependency instead of using it via Requires.jl? to the list above

Support for MPI.jl if configured to use the system MPI library.

Currently, the workaround is to build P4est.jl also using the system MPI, correct?

I don't think we should invest time into trying to get a better error message right now. We will change P4est.jl completely soon (as soon as possible), so I would...

Could you built MPI.jl and P4est.jl using your local versions, @jmark?

Can you rebuild the bindings with Julia v1.6? Currently, the version of CBinding that P4est.jl uses does not work with Julia v1.7 or newer.

Use `withenv` instead of manual setting and re-setting ENV-fix for GR

An even better approach might be to just set `GKSwstype` in our CI scripts

Check influence of the step size controller on performance for SSPRK43 elixirs

Yeah, that might be true...

Possibly interesting features of Julia v1.8

> what's the role of `Ref`s here? Our way of doing this right now, e.g., https://github.com/trixi-framework/Trixi.jl/blob/041c4dffe412de1bd7da79bbf830d9421ff32309/src/auxiliary/mpi.jl#L38-L43

Possibly interesting features of Julia v1.8

Yes, that's how I understand it.
