I was thinking it'd be amazing to have an option to add weather events! Or special events like blood moons and or different downpours and showers! It'd lend to the world-building aspect as it'll give the users the option to create special weather types for their worlds!
Like an example would be for DnD games maybe during a trip there would be a storm and it'd show on the map, or perhaps having a scene written where you can add a weather block in the side bar for specifying the weather types for future note!
And in Timelines you can create or specify weather types for the events that take place like for example when a war had taken place or a temple was destroyed you could also detail it by saying it was storming or it was some type of phenomenon that took place at this time, could also mark it as the first time this sort of thing happened on that day as well!
I think it'd be incredibly useful, especially since some are forgetful and don't want to either have to read through blocks of text just to find what the weather was supposed to be like and it'd be very useful I think for those who love creating deeper world-building!
I'm not quite sure how hard it'd be to implement but I think it'd be very worthwhile to a lot of users!
