Hi all, I noticed a new option during creating a new local table source for my DVL (snap-to-place project) - ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/a/b/abc342f2a9f246fa92edb79c244aa7b59f07dda4.png) I’ve never noticed this before, but the Thunkable docs seem to be updated with this ([Data Sources - Thunkable Docs](https://docs.thunkable.com/data-sources#2.-create-your-own-table) - Step #7) : ![image](https://us1.discourse-cdn.com/flex015/uploads/thunkable/original/3X/5/1/51ba0dcd5d1370caddd301138f125cf4c5972c9c.png) But I still don’t understand what they actually do - if my data source is “App” one, will it reset to blank table if app is closed? and persist/store data until deleted from app if it is “Stored”? If someone has any idea please explain to me… Thanks! * * * BTW, anyone experiencing outage in dvl layout creation? I’m unable to add a row/column as a list data viewer layout - it just shows the loading icon for 1-2sec and then does nothing. Is the platform under maintenance / updation currently? ---

👀 first glance would make me think they’re speeding up the interaction time with local tables. Related to your other post about how they are slow, perhaps this is a v1 to scoot around that limitation? ---

@matt_conroy Can you please shed some light & give us curious souls a rough idea on what this actually is? 💡 ---

@kartik14 Sure! The tl;dr on this is that when adding local Data Source, a user can now add it as an app data source (resets when user closes/re-opens the app) or stored data source (persistent, does not reset when the user closes/re-opens the app). Should be an update to our docs coming on this soon! ---
