Big fan of gron[0] and zoxide[1]. Gron for flattening and viewing JSON, and zoxide (z) for fuzzily jumping around on my system or on remote systems with z installed.

Also been using Rad [2] (disclaimer: am author) to replace my suite of Bash scripts and write new ones, quite happy with one atm which sets reminders e.g. 'remind 2h check the CI build' which will give me an OS reminder in two hours, I use it a ton at work.
