We should have some sort of ability to specify default behavior of jubilant w/re to display/formatting/locale. Esp. date formats are a pain, ui5 takes the very long and verbose notation as default which is really hard to parse for my brain. If we build this, we should have some sort of application default; then, ideally, per user defaults (how? we don't have concept of "user identity"), and per visualisation (this should then of course be stored when saving the query). This probably needs to be cut up on a number of different tasks. A good start would be to have a model with global, application-wide defaults. This can be initialized from a json model. Next step should probably be per-visualisation settings. This could be configured in the settings dialog, and stored when saving.
