If you’re creating a UI, and you realize that some part of it is prone to misclicks, but you think it’s not too bad, and you’re not sure whether you need to do anything about it, consider that people misclick even on UIs that are not prone to misclicks at all, so the misclick problem already exists no matter how good your UI is, even for people with no disabilities, and your UI can only make it worse. Therefore, if you notice a misclick potential in your UI, fix it.
