**User story:**
As a Wikidata editor,
I want to find the `mul` Labels and Aliases at a consistent place in the termbox,
so that I am always able to find it quickly.
**Solution:**
* Always show `mul` as the last language in the "In more languages" section.
* It is not relevant if the `mul` Label or Aliases are empty or not.
* There are users working with a lot of Babels. These Power users should be able to specify a position of `mul` via their Babels.
**Mockup:**
**Expected fallback:**
{F36845476}
**Notes:**
* We only want this for Wikidata for now. Initially we will not activate it in Wikidata either to allow for a soft rollout. So this needs to be configurable.
* A consistent place is preferable to 'mul' jumping around from entity to entity. We chose the bottom position as it is unproblematic even for non-Latin UI users and entities that should not use `mul`. Also, it makes the fallback functionality intuitive.
**Open questions:**
* Do we really want this for Properties?
* Is there a better way than using this for a soft rollout?
**BDD:**
Show `mul` where the Babels say if so specified in a user's Babels.
GIVEN a wiki with language code `mul` (no matter if this is enabled or disabled)
AND the Babel extension is enabled
AND the user has specified `mul` in their Babels
WHEN editing or viewing an Item on mobile or desktop
THEN show `mul` in the "In more languages" section of termbox at the position specified by the Babels
Show `mul` as the last language if not configured and not specified in a user's Babels, but used in the entity.
GIVEN a wiki where this is configured as disabled
AND the user has not specified `mul` in their Babels
WHEN editing or viewing an Item on mobile or desktop
AND the Item uses `mul`
THEN show `mul` as the last language in the "In more languages" section of termbox
Do not show `mul` if not configured, not specified in the user's Babels, and not used in the entity.
GIVEN a wiki where this is configured as disabled
AND the user has not specified `mul` in their Babels
WHEN editing or viewing an Item on mobile or desktop
AND the Item does not use `mul`
THEN do not show `mul`
Show `mul` as the last language if configured and not specified otherwise in a user's Babels.
GIVEN a wiki where this is configured as enabled
AND the Babel extension is enabled or disabled
AND the user hasn't specified `mul` in their Babels
WHEN editing or viewing an Item on mobile or desktop
THEN show `mul` as the last language in the "In more languages" section of termbox
**Acceptance criteria:**
[] Show `mul` where the Babels say if so specified in a user's Babels.
[] Show `mul` as the last language if not configured and not specified in a user's Babels, but used in the entity.
[] Do not show `mul` if not configured, not specified in the user's Babels, and not used in the entity.
[] Show `mul` as the last language if configured and not specified otherwise in a user's Babels.
[] for Items
[] for Properties
[] for mobile termbox
[] for desktop termbox
[] This is configurable to make it available only on specified wikis.
[] We have tested both configurations (enabled/disabled) on Test Wikidata.
