I'd love to use a terminal with similar features on linux
It's really interesting how OS X is the one that has a terminal emulator with the most features out there.
iTerm2 now comes with 24-bit colors, command completion popup, notifications, triggers, profiles, mouseless copy, split panes, search, and you can even have inline images/gifs all out of the box with zero or minimal configuration required. That's just awesome.
All of these features and iTerm2 still feels much faster than Terminator to me.
In my experience, the vast majority of web developers use OS X. Those of us doing server side and devops work spend a lot of time in the terminal
Actually that will be Windows with ConEmu. You can even run GUI apps inside the terminal with it.
Notably, keyboard-select allows you to cut/paste things into the X buffer from anywhere in the terminal scrollback using only keyboard shortcuts. url-select, conversely, allows you to cycle through any visible URLs and either open them in an external browser or copy them to the X buffer.
