A possibility to subscribe to Figma native events using the on/once handlers

[andrii-bodnar]

Currently, the library provides the on() utility for custom events, but native Figma events can only be subscribed to using figma.on() directly in my main.ts.

Current Problem:

figma.on("selectionchange", () => {
  // Must use figma.on() directly
});

There's no way to use the library's event utilities (like on() or once()) for native Figma events like selectionchange, currentpagechange, etc.

Proposed Solution:
Extend the existing on() and once() utilities to support native Figma events, or add new utilities specifically for Figma native events.

Benefits:

• Consistent event handling API across custom and native events
• Access to the library's event management features for native events
• Better integration with the library's event system
