How to use feedback on written publications efficiently? Whenever I submit an article, conference paper or other written document, I get tons of useful feedback from my supervisors and other PhD students. So far, I've made sure to adjust my submissions according to their good comments, and then just throw the feedback away. But I feel like I could use that feedback much more efficiently.

I would like to categorise/condense the feedback in some way that makes it easy to identify my weaknesses and common themes, and also to see whether I'm actually improving in all areas or there are some recurring comments.

Does there exist a good framework for this task? If not, how should I approach it?
Your writing skills usually improve gradually over time. It seems like a very natural approach to obtain feedback and improve papers accordingly,thereby learning important skills.

If you want to be more efficient/structured I suggest that you not try to collect and categorize all feedback you get but try to build up a collection of "Tips and tricks". What I mean is, that you could skim the feedback for general advice and useful tricks that seems to be applicable in more general form (such as "write the introduction from general to specific and write the conclusion from specific to general") and collect only these bits.
