 ## Background (the "t" script)
 
-Sesh is a predecessor to my popular [t-smart-tmux-session-manager](https://github.com/joshmedeski/t-smart-tmux-session-manager) tmux plugin. After a year of development and over 250 stars, it's clear that people enjoy the idea of a smart session manager. However, I've always felt that the tmux plugin was a bit of a hack. It's a bash script that runs in the background and parses the output of tmux commands. It works, but it's not ideal and isn't flexible enough to support other terminal multiplexers.

 I've decided to start over and build a session manager from the ground up. This time, I'm using a language that's more suited for the task: Go. Go is a compiled language that's fast, statically typed, and has a great standard library. It's perfect for a project like this. I've also decided to make this session manager multiplexer agnostic. It will be able to work with any terminal multiplexer, including tmux, zellij, Wezterm, and more.
