Better UX (more compact screen)
Now, if we use one type of activity, all is nice and easy to find and work with.
The problem is, if we use the Column, the concatenation of exercises makes complicate the navigation.
Maybe if Column is activated the content will be more compress or organise in a way that makes easy to read an navigate
Look the pictures, a full screen with just empty space or just 2 lines of information. Imagine a situation with 10 different activities together.. the scroll would be insane.
