If you've discovered that your teammate is editing the same file as you, it's quite likely that at some point you'll want to see their version of the file.  Using the Coactive Editor Gem, you can do this with just a couple of clicks:

1.  The Coactive Editor Gem will appear when Coactive detects that one or more of your teammates are also editing the same file:

2. Click the button to see a list of teammates editing the file and hover a name to see available actions:

3. Click View Joe's file and Joe's version of the file will open in a new editor tab:

Note that this will load the most recently-saved version of their file.
