Tabs On Left

Explanation

By enabling this setting, your favourite Tabs will be shown before the Salesforce Standard Home and Object Manager Tabs.

By default, your favourite Tabs are shown after the Salesforce Standard Tabs.

Technicalities

Implementation

Since the Tabs are kept into our own ul element (with id again-why-salesforce), moving them before or after the Standard ones (which are themselves kept into their own ul element) requires a simple insertAdjacentElement call on the parentElement of our ul.
