Hi Dalyoung,
Thanks a lot for the feedback! Glad to hear that my attempt at updating
this example can be useful!
On this note, I noticed that the code in my previous message fails when
there are multiple `ThreeColumns` regions. The code below seems to fix this
issue (although in a slightly hack-y way).
