It would be useful to have a setting to open the Vault Manager when launching Obsidian, instead of automatically opening the last-used vault.
Obsidian already supports obsidian://choose-vault, but using it as the default launch action requires modifying the Windows shortcut or Linux .desktop entry. These changes can be lost when Obsidian is updated.
A setting such as “Show Vault Manager on startup” would provide an update-safe way to enable this behavior across platforms.
