Documenting a minor annoyance here, but one I know a few other collections share.
If a collection database only has one localization (English), the user should not be prompted to select a language every time they open the schema config. It should just take you directly to the list of tables.
That extra click and extra load time it takes for the DB to display the list of localizations really adds up when doing a lot of work on the schema.
Hi Nate,
I’ve added this request to GitHub as #8384. 
The choose language selection dialog is also how you can add a language currently, so implementing this would also require moving that option somewhere else so it can still be accessed. As I note in the request, it could be moved near the “Change Base Table” button in Schema Config or to preferences.
Additionally, if you’re not already aware, you can save time working in Schema Config by navigating using the URL. The URL will end in /specify/schema-config/en/'TableName'/ for english language selections.
For example, using our demo fish instance, the Absolute Age table in Schema Config would have the following URL: https://sp7demofish.specifycloud.org/specify/schema-config/en/AbsoluteAge/
To switch to another table, you can simply change the last bit: https://sp7demofish.specifycloud.org/specify/schema-config/en/CollectionObject/
This approach will bypass the need to select a language or table through the dialogs!
Thanks Bronwyn!
The suggestion you gave (navigating just by URLs) I honestly hadn’t thought of. I guess I could just have a browser bookmarks folder of the config links to the most commonly edited tables as well.
