There was one called Terminator which had some tmux like features, split panes, broadcast, etc. It's not been maintained in a bit.

I used to use terminator for a long time, but i've switched to tilix (https://gnunn1.github.io/tilix-web/) with little pain.

I'll check it out.

Note: that Terminator I linked is a re-boot (I'll be back) so, I might give it another go as well.

I was a huge tilix fan for ages, but ran into an issue with long URLs being unclickable.
