This post is similar to Intelligent Pasting of Lists so could be merged if mods determine it to be the same issue.
See how Obsidian treats copying/pasting list elements that are indented:
Then see how Loqseq treats the same copy/paste:
Obsidian should follow a similar behavior to Logseq.
More on my use case: use Obsidian at work and we work from Google Docs or Notion primarily, but I often work solo in Obsidian for a long time before getting ideas out into Notion or GDocs.
We have lots of documents that are written in an outliner-style format. And when it becomes time to copy and paste from Obsidian, 99% of the time the first bullet I want to copy is not the farthest left indented bullet. So it means going through an entire document and manually deleting extra space.
