If any PowerToys feature deserves to be added to Windows, it's gotta be the Keyboard Manager.
However, instead of rebasing, I often git reset to the beginning and recreate the commits from scratch, using partial file commits (or staged hunks). IDEs/editors like VS Code make it really easy to stage an individual part of a file for the commit. The CLI way (git add -p) has always been pretty confusing to me.
EDIT: I hadn't actually seen much of the Vive Pro 2, it looks... comparable to the Index? Both price and feature-wise?

From playing around a bit, I've at least noticed that sortable headers have no focus indicator, the "sort column ascending" text gets included in the column's accessible name, and un-sortable column headers are read as clickable by screen readers.
I would LOVE a framework-agnostic table library that's both lightweight and fully accessible. If there's a chance for Grid.js to take this in its philosophy, I would be all in!
On a related note, Neopets has also been migrating their huge catalog of Flash games to HTML5 over the years. I have no idea how that's going though.
