Any recommendations for others?

I recently wanted to find the best solution for world building, came upon an open source Russian app called starc.app that looked good, but found out you can replicate all the features essentially with Obsidian Syncthing, a good folder structure, some templates, and the following extensions:

Core system

• Dataview
• Templater

Worldbuilding UX

• Juggl
• Canvas or Excalidraw

Writing & story

• Kanban
• Outliner

Compendium visuals

• Minimal Theme
• Style Settings
• Advanced Tables
• Media Extended

UX polish

• Sliding Panes
• Hover Editor

Joplin works well with Nextcloud, WebDAV, and has good extensions, I find better for different types of note taking alongside Saber.
