How do I save an analysis?
You can save any of your self analysis lines by clicking on the 'save' button in analysis:
When you are in a Daily game, and enter self analysis, the save button will appear once you make some moves. If you find a line you like, you can click 'save' to make sure you can view the line later.
You can find your saved analysis by going to your archive and clicking on 'saved analysis' on the right menu.
I appreciate Chess.com working on the ability to have a computer analyze games to help with our chess skills, but as the picture above points out, it has a long way to go. Qe1 is good enough for mate.

When i use this option after analyzing a game, where can i view the analysis again?
