Genuine question from iTerm users: which of its many, many features do you use most and find most valuable? I have always had it installed, but Terminal.app from macOS seems to have been enough for me. Maybe because I’m always using tmux anyway and that covers some of iTerm’s advantages. But I’m still curious about iTerm.
There's the tmux -CC control mode support that was mentioned, which combines best from both. Leader key support that arrived in this version might enable even greater Tmux integration.
I like how easy it has been to manage Unix terminal keys without giving up non-US keyboard altogether. Other Unix/Linux terminal stuff like middle click/tap paste. Search is good. Hotkey window ("Quake" mode") is a fun one, but never seem to remember to call it. Contrast adjustment to tweak themes for readability. Smart Selection for urls and the like.
But I've been an user for many years, so hard to look at the experience through features.
Split panes without using something like tmux for me. I like having long running processes like a bundler in watch mode visibile, but with a keyboard shortcut to "maximise" a single pane if I need more space (cmd+shift+Enter).
Tmux integration: tmux is running remotely in control mode and local iTerm2 is managing it. This way tmux panes and windows are mapped to native windows and iTerm2's split panes. Makes remote feel like a local machine
