The addition of a few features to the right click menu in the assets panel would definitely improve productivity.

1. Rename - The ability to right click and rename objects in the assets panel would greatly improve the ability to organize objects instead of the current method of navigating to list view and then renaming objects.

2. Edit - The ability to right click and edit any asset (as is currently possible only with colors) would be extremely useful for assets that are used infrequently in large projects that would have to be found manually and changed on the canvas.

3. Export - Exporting assets directly from the asset panel would be a fantastic addition as well.
