It looks like you have done a great job with lnav - it's impressive. I know how much work has gone into LogViewPlus and you must have made a similar commitment. I thought I was the only one crazy enough to want to solve this problem. :-)

I would be happy to chat to a like mind if you are interested. You can contact me here: https://www.logviewplus.com/contact.aspx
