This is the tenth time I stumble upon a controversial blog, write a large comment that'd be useful both to the OP and other people, and when I finally post the comment Codeforces tells me the post is deleted and my giant rant doesn't get saved. I usually breath in and out and get over it, but this time I figured out
I have spare contribution to post a complaint I can share my thought with the community.
It'd be great if comments were saved to drafts just like posts. This would be useful in case of network problems or power failure too, and would just improve UX overall.
