5.9 Micro-interactions (hover, tap, drag states)

I’m working on a project about [describe your domain/product/idea]. I want to design micro-interactions to improve usability. Can you help me with: 1. Suggesting key interactions to enhance (hover, tap, drag, notifications). 2. Giving examples of subtle but effective animations. 3. Highlighting rules for timing, easing, and accessibility. 4. Suggesting how to test micro-interactions with users. Format output as a list of recommended micro-interactions.
