I think the best layout is the one that works for you. There’s likely always going to be something to change to make it a little better but I wouldn’t worry so much. If what you’re using is working then keep it. I haven’t used my own deck in a while but here’s what I’m using, and it works great for me.
I’m by no means suggesting that you stop using Anki, but I was wondering if you’ve heard of a website called Kitsun? It’s also a flashcard SRS that allows you to customize layouts, and there’s lots of new features in the works. If you wanna check it out, here’s the thread:
At any rate, you might also find this video by Leebo helpful. In it, he talks about how to make good flashcards, or the common pitfalls to avoid.
I know there’re people here that have lots of experience related to customizing Anki cards… myself I’m super fond of my own. But looking back, If I wasn’t that attached to the way my cards look now I would go with a simpler and more efficient way (which is probably the only way I see Anki surviving more than 2 years in my life )
I would strive to AUTOMATE the creation of cards almost from the get go.
Yomichan has a function to do this (so when readingon the web or watching shows with subs on Netflix for example you could make the cards right there) and even more I would try to set up an e-reader device (Kindle for example) to also create cards on the go, or at least make the transfer from reading to vocab reviewing as expedited as possible.
I’ve made a routine for putting WK vocab into use ASAP … but overall reviewing vocab it’s much more effortless when I can relate it to the place, show or story from which it came from… hence the worth of really make vocab reviewing closely related to immersion.
