Support for vertical tab stacking / portrait mode

This idea of FR came from sliding-panes plugin github FR (link)

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 :slight_smile:

This is also very important for the mobile application Obsidian.
