One of the hardest things to code manually is a shared focus tree (e.g., a Swiss federation tree). The new maker has a "Shared Branch" mode. Design it once, and the tool duplicates it across multiple nations with correct namespace adjustments.
Crucial for political choices (e.g., choosing between Fascism or Democracy).
The centerpiece of this extension is its dedicated "Focus Tree Editor", which can be launched via the command palette ( Ctrl+Shift+P and type "Focus Tree Editor") or by clicking the Shield icon in the sidebar.
