- Added StorageConfig class to replace ugly arrays
- Implemented StorageService and StorageController for Global and User
storages
- Async status checking for storages (from Xenopathic)
- Auto-generate id for external storage configs (not the same as
storage_id)
- Refactor JS classes for external storage settings, this mostly
moves/encapsulated existing global event handlers into the
MountConfigListView class.
- Added some JS unit tests for the external storage UI
Whenever file actions are registered later, now the file lists are
automatically notified.
Added FileActions.addUpdateListener() to be able to receive such
notifications.
This removes the need for apps to manually call FileActions.display()
after registering new actions.
This fixes issues with race conditions when file actions are
registered after the file list was already rendered.
