I'm debating the pros/cons of opening a live chat window as a popup vs. a new tab. The context is that the user is in a shopping cart. A chat invitation slides up, with a button that says "start a chat".
Due to limitations in development time, we can't pin the chat window to the current window. We're launching imminently, and we have 2 options:
- Pop up the chat window as a popup, on top of the shopping cart screen
- Open the chat window as a new tab
What are the pros and cons of these options?
