[DEA-29] Support for vertical stacking / portrait mode

[flancian]

Ahoy! First of all, thank you for the great extension :)

I use Obsidian in portrait mode and unfortunately this results in awkwardly tall panes by default using this extension:

It would be great if one of the following was available:

1. vertical stacking instead of the current horizontal.
2. (better) NxM mode, or less generally two horizontal stacks one on top of each other :)

Is this planned/would it be useful to others?

This is also very important for the mobile application Obsidian.
