Where & how to create custom widgets & routes with Mercur 1.4.0+?

[ecosse3]

Hi, in previous versions of Mercur, the admin panel part of Medusa was customized in /src/admin directory. Now the admin panel is separated into a separate repo; this directory is empty. I made some customizations to the admin panel via Widgets Injection Zones and separate routes under /src/admin/routes in my current Mercur repository, and now I want to upgrade to Mercur 1.4.0+.

Where should I create my custom admin routes & widgets? Should it be in backend /src/admin/ directory or should I customize admin panel, which is now in a separate repo?
