Add Groups for Timelines & Characters

[AutumnRivers]

Is your feature request related to a problem? Please describe.
I'm currently working on a visual novel remake in Godot, using Dialogic. The main issue here is that the visual novel I am remaking is massive. Multiple books, multiple chapters, a whole slew of characters. The current issue I have right now is that the editor shows all these characters and timelines together, with no option to organize them.

Describe the solution you'd like
The ability to group together timelines and characters together in the main editor. This doesn't really have to change anything with how files are handled - this can be nothing more than a cosmetic change. Similar to how variables can be grouped.

There would be a separate icon next to "Create Timeline" and "Create Character" that would allow the developer to create a group. They could rename this group to whatever, and put either timelines or characters in it. Both, if they so wished.

Describe alternatives you've considered
Right now, I organize everything I need by starting each timeline/character's name with the category they're in. ex. Book 1 Chapter 1's timeline would be named Book1_Ch1, and Character A would be named char_CharacterA. This still leads to a fairly messy look, but it's better than nothing.

Additional context
I'm currently using Dialogic 2. As I stated above, this can be just a purely cosmetic change, and still require the usual unique identifies across all groups.

Thanks for your issue.

Just a small note, variable groups are implemented using Dictionarys and are more than just cosmetics.

My mistake, I used the wrong number.
There is only two proplems in computer science: Off by one errors.
Or something like that.
