I don't like adding UI's. I prefer to make my own on the fly, fiddle around with stuff until it works the way I like. I view UI as an unnecessary, opinionating addition.
Here I'll just describe how I'm using stuff.
I have a fish function called today, it runs todayscript.rkt, and >'s it into status. Another function called agenda, that cats status to show me the day's agenda.
I use tmux. One window is always split into three: a vim, a racket repl, and a terminal. I prefer loading things into the repl to run them, rather than adding output to the file to be executed.
Someone else could do things entirely differently, without being constrained by my own preferences for UI.
Basically, don't expect much in the way of user interface except at the most minimal levels.
