In the last 18 months or so my terminal use has exploded. From being a place where I mostly navigated the file system, ran a server and did some very light nvim use, to my entire workspace, connected to multiple machines, where I spend most of my day.
This is the starting point we're using for designing the @superlogical multiplexer, and we're borrowing ideas from another app that blurs the local and remote, long lived sessions and throwaway tabs: the web browser.
And the first thing I wanted to borrow: favicons, for your terminal apps.
We call it the Deck icon (like a deck of cards), since it needs to represent your own layout of (potentially) multiple running processes.
