Ours used gridpane
Neither, we used Group group = new Group(); and basically thought about it as a canvas putting things in specific Locations
We used CalendarFx.
How did you import and implement calendarfx?
We struggled with it so much but still could not figure it out how to use this library. We thought it's solely built for Maven something, not Eclipse.

Yes, but to be honest, it is kinda complex to implement.
