Is it possible to set a timer to close certain notices automatically?

Hi Marc,

1) Yes, it’s possible. You can use the Auto-close option.
It allows you to setup the number of seconds that it will take to close the pop-up. You can set what kind of notices (error, success, or info) will auto close. But you can’t config a different time for each one

2) Most of the customization can be made using the Customizer. Now, if you really want to use some custom css there is no problem. it’s possible to override it. For now the popup can only be centered 🙁
Maybe with some custom css it would be possible.
