Highlight newly-created items via UI animations

[seancolsen]

Let's consider the flow of adding a new schema from the database page. After the user submits the modal form and the modal closes, the user is still on the database page looking at the list of schemas. We'd like to use some CSS animation on the newly-created schema card to help the user locate it amongst the list of schemas. We should also scroll it into view if necessary.

The animation should be useful, subtle, and tasteful. It is to be improvised during implementation.

We should apply this same animation when other entities are created too. For example:

• Roles
• Collaborators
• Databases and tables (in conjunction with Don't "open" newly created databases/tables #4055)
