Programmatically focus CommentThread Input

[j-erasmus]

Issue Description

Currently, there is no direct method within the VSCode API to programmatically focus the comment input field. This feature would be highly beneficial in extensions that rely heavily on commenting workflows.

Feature Request

Please consider adding a method to the CommentThread API that allows extensions to focus the comment input field programmatically. This functionality would make it easier for extension developers to guide users directly to the input, particularly in use cases where immediate user input is desired after triggering specific actions.

Use Case Example

An extension that helps users provide inline comments in code might want to:

Automatically open the comment input field at a specific location.
Programmatically focus the input field so the user can start typing immediately, without needing to click into the field manually.
By allowing programmatic focus on the input field, the workflow becomes more seamless and intuitive for users.
