@s-kyy So this looks like a little bug in the way the workspace is handled currently.
If you have multiple vertical splits and you drag one into another as a horizontal split, you now have a horizontal split inside one of your vertical splits. vertical -> horizontal. Makes sense so far.
If you drag all of your panes in this way, you now have a setup with one vertical pane containing multiple horizontal panes.
Then when you try to drag one of these panes back out again, you can’t really, so you end up creating a new vertical split and you now have vertical -> horizontal -> vertical.
If you drag all of your panes in this way, obsidian is smart enough to get rid of that horizontal pane altogether and move everything back up, but you still end up with vertical -> vertical.
Combining that with the fact that Andy’s mode only applies to the root level vertical panes, it means it won’t apply to the inner ones and you end up with the bug you’ve mentioned.
I have reported this to the devs, and they have confirmed that it is a bug, and will hopefully fix it in a future version by collapsing any splits of the same direction into one, so vertical -> vertical will become just vertical, hopefully solving this issue.
Sorry for the wall of text, but hopefully my explanation makes sense. Thanks for pointing this out
