* Application storage meant for small and medium large internal app states.
|

|
|
* Possible data would be non user editable cached values like auth tokens.
|
||
|
|
* Note:
|
||
|
|
* 1. Please consider using a Settings key first before using the storage adapter!
|
||
|
|
* 2. The values may not be synced across multiple window instances.
|
||
|
|
* Don't use this for IPC.
