Feature Request: Auto-Trigger Parameter Hints When Cursor Enters Parentheses

AFAIK parameter hints are only show when:

  • Typing ( or , within a function
  • Invoked via keyboard shortcut

It would be nice if it was possible to have the parameter hint shown automatically if the cursor is inside () and automatically hide the parameter hint when the cursor leaves ().

This would eliminate the need of manually triggering the parameter hints.

Contributor guide

Research direction
Investigate how parameter hints are triggered in VS Code's language features. Look for the logic that shows hints on typing '(' or ','. Modify the editor cursor change handler to show hints when cursor enters parentheses and hide when leaves.
