Something that bothers me about #Obsidian is that (to my knowledge) it’s not possible to open a #Markdown document outside the vault. You must import the document into your vault before being able to edit it.
I find that annoying. It should definitely be possible to open a document outside the vault/workspace to view and edit it. It will be a feature I will add to my notes app.
I think, when opening a document outside the workspace, it should open in a separate window that doesn’t include the sidebar but only shows the document by itself.
Otherwise I need to figure out a way to make it clear for the user which files are part of the workspace and which are external.
