Questions about the hourly tracker

Hello! This is my first time doing work with thw hourly tracker so I want to make sure I don’t mess it up lol. So I have a few questions:

1. Does it track whatever window I have open or do I have to change it, if I go from Google Sheets to Slack etc
2. I use two screens, does it know how to switch between them?
3. I have a lot of other accounts besides my client’s one, is there a way to obfuscate part of the screen when I open up, let’s say, a Google Ads account so they wouldn’t be visible?
4. Does it record sound? :D Like if I’m listening to music at the same time do I need to make sure it’s not anything embarassing
5. Anything else I should be aware of?

Thanks a bunch!
