[Feature]: Don't destroy / reload datagrid when opening & closing product, order etc. to improve performance

[simon-online]

Description of the feature

Problem:
Currently when you view a datagrid for example the products list and then click on a product row the product details screen opens and the datagrid is destroyed which means when you click the back button at the top left to return to the products lists it needs to be reloaded again which takes a second or two before you see the list. On top of that any filters that were selected previously are not preserved and then need to be selected again. This creates a slow and unproductive user experience.

Proposed solution:
Instead of destroying the datagrid in this situation the row details screen should just open over top of the datagrid. So that when you click the back button at the top left to return to the datagrid all it does is close the row details screen so you can see the datagrid underneath and the data for that particular row is updated from the row details screen and checked to see if it still matches any selected filters. This should be a much faster and more productive user experience that also preserves any selected filters.

Acceptable criteria

[ ] A user should always see a datagrid as it was whenever they close the row details screen eg. the product details screen without waiting for it to reload again.
