1. Problem

When users import many namespaces using the UI

• it does not preselect the namespaces when the format is different to {namespace}/{languageTag}.{extension}, so the user has to select it manually, which takes time (Bulk-import actions #3172)
• it's slow

Bussines impact
The import is usually the first thing users interact with. We don't want to lose them, so import UI is extremely important.

2. Appetite

How much time do we want to spend on this?

3 days

3. Solution

How do we imagine solving this problem?

• Automatically preselect the namespaces according to the file structure (by the folder name or according to the convention for the imported format)
  • You will need to somehow detect what structure it is
• Use profiler to inspect what's making importing with namespaces so slow. There will be probably some n+1 problem
