This can be interesting for simplified usage with large timesteps where changes in storage don't matter, except for large reservoirs. Also it would be nice to use this as an...

I'm thinking about a configuration option like this: ```toml [solver] steady_state = true # optional, default false ``` When `starttime == endtime` this would just do a steady state run....

In https://www.geopackage.org/extensions.html there is the [Styling and Symbology Extension](https://gitlab.com/imagemattersllc/ogc-tb-16-gpkg/-/blob/master/extensions/5-portrayal.adoc). Though the fact that that is an archived repository with a notice "This subsection is under discussion and may change radically."...

Closing this. It's not complete yet, but useful and sometimes being updated.

In #2137 our Parameters struct was manually split into ParametersNonDiff, DiffCache and ParametersMutable for DifferentiationInterface. ``` @kwdef struct Parameters{C1, C2, C3, C4, C5, T} p_non_diff::ParametersNonDiff{C1, C2, C3, C4, C5} diff_cache::DiffCache{T}...
