Added context actions for importing and exporting JSON representations of domain objects. Added FileInputService for triggering file picker and retrieving uploaded data. Also added a File Input form control for integration with MCTForms.
This change is based on the following code review:
- Display the entire list of timezones, regardless of what's currently entered.
- As soon as the user typed (or deleted chars in the input) then that filtration would take over the list display
open #638
Added custom radio button control and modified
PlotOptionsController / plotOptionsStructure
accordingly; spacing, borders, etc. are
all as finally intended;
