Some old bugs still haven’t been fixed.
Using a Layouts effects how sub-layers is behave
1A. Here the group has no layout and sub-layers can be resize as expected
1B. Holding Option ⌥ and dragging the layer wider let’s you resize it horizontally while keeping it centered.
2A. Here the group has a vertical, top-down layout applied
2B. Holding Option ⌥ and dragging all the sudden doesn’t work.
Takeaway
Having a layout should never affect the way a sub-layer behaves (especially when it’s a vertical layout and you’re making a horizontal change to the sub-layer). The current remedy for this is to, first remove the layout from the group, second make your changes, then go back and add the layout again. Slow and annoying!
There is a way to Pause Smart Layout, but it’s buried in the Layer > Layout > Pause Smart Layout so no one will ever find it.
Smart Layout is so BAD I want it permanently paused. I have absolutely zero use for it. It only complicates the way I interact with layers. Even when it works it’s inherently unintuitive. This example is only one of the many bugs with it. Please revert Layouts back to the way they used to work, where they only affected instances of a symbol. Not the content of the master symbol.
Option ⌥ drag is a standard OS level behavior (it works on all app and finder windows). breaking this behavior is very annoying and clumsy.
