Hello.
You need to seriously improve and expand the capabilities of the built-in calendar. It is also necessary to add a Gantt chart to it. Thank you.
Thank you very much for your proposal!
The built-in calendar will be improved, and we'll also support to integrate to phone calendar. But Gantt chart may not be considered for the present, for it may make things complex.
If any further ideas, welcome to discuss with us any time.
Nice day!
