Hello Taco,
Regarding the carousel alignment: when an Image Carousel is placed inside tabs, the first tab usually loads correctly because it is visible on page load. The other tabs remain hidden initially, so the carousel cannot calculate the proper width until the tab becomes active. This can cause the alignment difference you are seeing in tabs 2, 3, and 4.
I will forward this to our development team for further review.
For your second question, linking from another page directly to a specific tab (for example opening tab 2 or tab 3 automatically) is not available as a built-in option. It normally requires a small custom script to activate the target tab.
Please, hire a developer for the second part.
Best regards.
