That’s one thing the article forgets. Going with a click rather than hover means you need to implement the “one click to select, double to activate” if things can be activated inadvertently with a single click.

I’m familiar with this issue as I’ve been trying to abandon excess hover effects and switch to clicks in apps I build on web stack. It’s difficult since most good UI frameworks rely on hover effects, and requires care in preventing accidental actions from a single click if you want your users to go with your paradigm and not hate you.
