When creating a new translation users select an article to translate. Currently, it is supported to select an article by title (and redirect names). However, that is not the only way to refer to articles and we can facilitate the search of articles by making the input more flexible.
We should be able to start a translation for the "Pad Thai" article by:
- Title. Pad Thai
- Redirect Padthai
- URL. https://en.wikipedia.org/wiki/Pad_Thai (possibly setting the source language to English in this case)
- URL title. Pad_Thai
- URL with namespaces. Wikipedia:WikiProject_Food/Translation_task_force/Pad_thai (assuming it is an excerpt of the article to be translated, similar to the case described in T86744#1569794)
- Wikidata ID. Q730298
The specific case of supporting URLs was mentioned here.
