Hi there RobotCandy,
In iOS 16, you can arrange Safari tabs either in a Tab Bar configuration, or in a Single Tab configuration. The Single Tab configuration is the way tabs were handled in Safari prior to iOS 15.
In addition to using the Tab Bar or Single Tab configuration, you can also use Tab Groups. Tab Groups allow you to categorize tabs for a similar subject together in one group, so you can easily find the information you need. For example, if you're planning a vacation you can group any research you're doing for your trip so you can easily find the information you need later.
More information on using tabs in Safari can be found in the following Apple Support articles:
If the specific tab organization option you are looking for is not discussed in those resources, we encourage you to provide your feedback to the appropriate teams at Apple. You can do that here: Feedback - iPhone - Apple
Best!
