A few weeks ago I released a very simple dynamic action plugin: AnimAPEX.
It consists of 75+ animations that you can apply to any APEX component.
Want to shake an input when the password is wrong?
Want to flash a report that has been refreshed?
Want to spin a button when it has been clicked?
AnimAPEX is easy to use and it will bring life to a boring app.
It's open source and free.
Inspired by Animate.css
