I'm keeping a lot of similar tabs across reboots (organizing them using TreeStyleTabs). Tons of Slack, Mail client tabs, ... without meaningful title prefixes. I'm now using your extensions for assigning titles specific to URL prefix (thanks to your beta regex matching). My brain feels so relieved.
Kind of cumbersome to put in place, but the best option so far!
Would definitely appreciate the ability to modify/add regex more easily, but this is already so useful.
Thank you a lot!
