Use case or problem
On mobile, Obsidian loads the last-used vault on launch, which can be frustrating if you intended to quickly open a small vault but a large, slow-loading vault was the last one opened. This can prevent one from even trying to use Obsidian if they want to load a vault quickly, but can’t remember which vault they had opened last.
Proposed solution
An app shortcut menu (when you long press the app icon) that has the option to select the vault to open.
Current workaround (optional)
I have resorted to renaming my large vault so Obsidian can’t find it on launch, then rename the folder back after Obsidian has launched.
Related feature requests (optional)
I wasn’t able to find any.
