Is Google Chat Thread Switcher safe?

Adds a topic drop-down for navigating loaded threads in Google Chat spaces.

This extension adds a drop-down list to Google Chat spaces that use multiple threads/topics. You can select a loaded topic to scroll to its input field, see unread topic titles in bold, and briefly view the current topic title when clicking in a thread. Threads that have not loaded in the chat view do not appear until you scroll and load them.
