When editing string resources, an empty value when searching brings back all resources. It would be nice for anyone who saves an empty value to have a way to filter the empty resource values. There are a lot of resources to search though to find any you saved as empty. Maybe phase 2.

I don't see the purpose of this, but if it is implemented tt should be a setting to allow storing blanks.
It's a pretty good indicator that the key is rendered when a translation is missing.

To allow storing blank as default can be misleading and confusing.

Also with this allow the entry of spaces

formattedattributes.priceadjustment has a space at the front (once you take the space out you cant put it back)

I can fix it in mine as I have a custom string that I am using to display and I added the space in the code
Maybe this is the better fix if your not doing anything about the other issue above

There are 3 strings that start with a space
FormattedAttributes.PriceAdjustment
Products.ProductAttributes.PriceAdjustment.PerItem
ProductAttributes.Quantity
