If we extended a base app in the past with 2 additional tabs and then introduced a layout app without those two tabs, would the extension app still have any effect on the UI?
Application layouts only control the base app they’re over, they don’t affect anything in the extension app. At runtime, the layout is applied over the base app, and the extension is pulled in separately as its own tabs.
So if you added two tabs through an extension app in the past, those tabs will still show up, even if your layout app doesn’t include them (and it won’t, since it only applies to the base app). Layouts can change how the base app looks, but they can’t hide or override anything added by an extension.
So yes, the extension app will still affect the UI whether you’re using a layout or not.
@Victoria, let me know if there’s anything you’d add.
