Problem: When reviewing an IP's contribs, admins have to look in block history to see if there have been any recent blocks. When dealing with ranges (especially /64), this problem is worse. To see rangeblocks, admins must add /[16,32,48,64] and then go block (not block log because that only works on the base IP, not one within the range) to see recent rangeblocks. Even to see past warnings to editors in a range, admins must go to the range, scroll through and find individual IPs whose talk pages aren't redlinked, open a bunch of them, and see if there's been escalation of warnings over a recent time frame, and then go back to the first IP and warn accordingly.
Proposed solution: Add recent block information on contribs pages for admins to see, similar to recent change to Twinkle's block popup window, including rangeblocks. A similar feature on the contribs or talk pages for warnings should be great.
Who would benefit: 管理者
More comments: This would be particularly helpful for dealing with LTA cases and vandals who jump IP addresses to avoid racking up warnings on a single IP.
