show/hide or open/close stack. What is good practice?

[Tiemo Hollmann TB]

Hello,

if I have stacks, which are frequently shown, like dialog windows, what is
good practice. Open once and only show/hide, when using? Or should you close
those kind of stacks always and toplevel/modal them again every time when
needed? When I need to change anything in those stacks on the fly, like
button labels, I open them only once and hide/show them when needed.

Is this just a personal preference or is there a guideline on "how to" in
LC?

What do you think about this?
