I think "vanilla" terminal users such as myself (e.g. I don't do a bunch of screen/tmuxing, I don't code in terminals etc) probably are not the target audience.

I've had zero issues with standard macos terminal ( once I realized how to speed up key repeat in system settings that is), so I assume I don't need this.

Same club here. I feel comfortable even with the crappiest terminal out there, as far as it allows me to write commands and read/copy output. Even the terminal in the Inferno OS felt good enough for me, like 20 years ago.

Makes a lot of sense, I fall into the same bucket as you so thank you for the response. I use the terminal to start up services and issue git commands. Beyond that, not too much.
