The Markdown Format Importer is great, but a converter/exporter to change wikilinks [[filename]] to the more common [filename](filename.md) across the whole vault would be wonderful.
[[filename]]
[filename](filename.md)
I see “Export to standard Markdown” on the Obsidian Roadmap. It looks like it is actively being worked on.
Obsidian already support the option that when you type a [[]]-notation it is automatically converted into -notation. For the files you already created you will have to write a script to do so. May I ask why you would apply the -notation in an Obsidian only environment?
