Hey, Thank you for your feedback. I’ll look at them, but right now, I have a quick tip for 3.
As you probably noticed, this app is strongly opinionated, and that’s why based on GTD (and Things app) inbox list is called Inbox, so I’m not planning to add an option to change that in UI. But you can easily do that in data mode. Connect your playdate in data mode, head to data/com.hydrasoftworks.pocketplanner directory, and open todos/data.json in a code editor like VS Code or Notepad++. You will find the line "name":"Inbox",. You can change Inbox to something different there.

In that case, I’m strongly recommending https://www.goodreads.com/book/show/1633.Getting_Things_Done for you. :) Speaking about productivity, this may be the most important book that I read (and I like productivity books). It’s not mindblowing, but I’ve been using GTD with https://culturedcode.com/things/ for many years, all thanks to reading David Allen’s book 15 years ago.
