add default layers in Earth Engine

At the moment, it is not possible to load another default layer than the L8 Greenest pixel TOA.

However, if you have a trusted tester account from GEE, you can easily save your workspace as JSON and re-import it at any time. It is just a work around but it is easy to implement:

• in GEE load the data layers you want, with the band combinations and the time period of your interest
• go to "Manage Workspace" tab and open the Import/Export option
• save the JSON text somewhere

Next time you have a window opening in GEE while using Collect Earth, sign in as Trusted Tester, open the "Manage Workspace/Import-Export" and paste your saved JSON inside, all your "default layers" will appear.

Similar to the JSON solution, you could also retrieve the workspace URL from "Manage workspace" > "Share workspace..." and it will address you to the workspace configuration at the moment of producing the URL.

Alternatively, so far only the current workspace session can be saved.
