When using the Global Create you can create a record without setting a parent. For new users this can lead to them create records such as opportunities without parent records by mistake. A prompt to say you haven't set a parent record when creating the opportunity would be helpful.

Should make this a banner on any record with no parent saying it has no parent with a link to the parent selector
