Existing implementation of Scheduler component has a very limited customization support. To cover some real use-cases we need:

1. Conditionally hide Scheduler Header and Footer. This is possible with CSS, but still makes sense to have props for that.
2. Customize tooltip content when hovering on the event. Currently tooltip is a one line text, but adding support of a larger popups on hover would allow to show additional info associated with that event. Please consider adding a prop to pass custom component for tooltip/popup rendering (similar to how Custom cells work in Kendo Grid)
3. Customize event component. Is there a way to have multiline text in the event component? Currently it is way to limited to show custom content e.g. adding custom icons is impossible.
4. All events in the same group have a same color when displaying. Please consider adding individual color support for each event. This would help to support error states for events.
5. Custom onDelete/onDoubleClick handlers. We would like to have custom implementation of Delete confirmation and Edit form.

Please advise on how to overcome those limitations as a short term solution and consider adding more Scheduler customization abilities to your Roadmap.
