Writing software

Hello, writers and poets of SpaceHey!

I have a question to ask,

Do you happen to know a good writing software that can help me write and connect the dots and timeline?

I've heard of Obsidian but I can't seem to understand how it works.. and I would like to make things easier for myself and not have to manually do everything.

If you happen to know anything or any software that could possibly help me out, I'd greatly appreciate it!
