[yogeshvachhani]

Is your feature request related to a problem? Please describe.
I want a way to share some data between app without having to pass them in URL.

Describe the solution you'd like
It would be great if there is facility for user to declare Variables at Workspace Levels and also at App Level.
The variables so declares at Workspace level should be accessible from all App in that workspace and all the variables declared at App Level should be accessible through out that app.

There should be facility to persist the Workspace level variable so if a user refreshes the browser they should not go blank or revert back to the declared state. In PHP we call such variables Session variables and they are stored at server level and not at browser level.

In case of App Level variable it would be great if there is facility to store them as cookies on user PC. This way we can use them to remember certain information in the app. And when the user comes back to the app restore the saved information. For example in an App there is a table control and user it on say 5th page. Now we can save this information and when the user comes back to this app restore the settings so the user can start working where s/he left off.

Additional context
The search feature in LowCoder has suggested the steps to follow and I think this will give some idea on how to implement this feature.
