Sounds like a good idea to me. I'm not nearly as organized.
It is partly an organisation thing, so you can get a full picture of what everyone is thinking about a specific element, but it's also because I'm really thin-skinned. When I read a critique I skim right past the compliments and zero in on the bad parts, and then I'm all upset and at risk of acting like a whiny prima donna. Breaking down the critiques helps me to process rationally and give the positive stuff as much weight as the bad.
When I get tough critique I also try and remind myself of a few things:
1. Good enough is fine. Perfect is for later.
2. Everything can be fixed.
3. This is the millionth draft of this chapter. There will be a millionth-and-one. It's not the be-all and end-all.
4. People still love me even if they don't love my work.
5. At least it's spelled correctly.
So, focus on the positive too, and keep everything in perspective.
