I've always loved and used flashcards, and relate to this article. I have built my own learning tool based on concept maps, which was inspired by Joseph D. Novak's book "Learning How to Learn". Concept maps are focused on how large networks of concepts connect to each other forming large graph spaces. One of the key problems after creating or encountering a very large map, though, is how to approach them in chunks. So I built a flashcard-inspired feature that chooses a concept at random and focuses your view on just that concept and its directly connected concepts. It's effectively a conceptual flashcard generator. You can check it out here: https://thinkingtools.software/concepticon It's a (sorry, Mac only at the moment) desktop app that uses plain text files in a format you can easily edit yourself in any text editor.
