I’m not sure how the current defaults are chosen, but for me personally, I don’t get the workspace that I want to be the default, and I can’t seem to figure out how to change the default. (The default project is always blank)… I am more concerned about being able to configure the default workspace, but being able to configure both of these in an extension options page would be useful.
If you read the recent reviews on the chromestore for your extension, you will see others are asking for this too.
I discovered this similar topic, and it made me realize that being able to configure defaults would also be useful for the people using the asana extension through the context menu rather than the keyboard shortcut. (Which is how I use it)
