 - The preferences pane can be found in the same left-side menu as the other Overleaf settings. 
 - You can run multiple instances of Native Overleaf, allowing you to keep multiple projects open at the same time and receive notifications for each project. 
 - The word count tracker tracks the total words in the project, so includes anything written by other authors. It counts the words in the compiled PDF, hence it must be recompiled to reflect recent changes. 
+- The word count tracker uses the local date of your system, hence inconsistencies may arise when switching time zones. If necessary, the word count can be reset using the button in the preferences pane. 
 - Notice on notifications: For notifications to work, the app must be allowed to by your system. You will only receive notifications for projects that are opened in the background, so you will not get notifications while working in a project. **Important**: to get notifications for chats, the chat window must have been opened at least once after loading a project (you can close it again). This is a limitation of the way we listen for new chat messages. If someone has a better idea, please get in touch.
