TL;DR Making ctrl+z and/or an undo button in the UI universally available would be a big improvement for overall usability and workflow for both new and longtime users
When helping an (older) family member learn to use anki for language learning, they were often making mistakes when making new cards, and it was hard for them to remember how to navigate the menus to the card they just created to fix the mistake. An undo button or being able to use ctrl + z after creating a card would be a big help. This undo button would also benefit new users in the review section, although I’m aware that you can use ctrl + z while studying.
I’ve personally been using anki for Japanese for a few years myself and often find myself pressing ctrl+enter just as I realized I forgot to include audio or something. I know you can navigate to the last created card with ctrl+h and double enter, but it would be such a big improvement to be able to undo the last created card and be able to work in the card editor just as it was before creating the card.
Thanks in advance for your consideration!
