It will be nice to be able to see only objects (entities, functions etc.) only from selected schemas. Currently all functions, for example, are in one list even if they belong to the different schemas. It should be very useful for all databases that have concept of a schema.
the most convenient way to filter objects by schemas is using Model Explorer. First you need to display the objects Full Names (do this by selecting the option from Display Toolbar, the option Captions should be selected by default). Now you can simply type the schema name into the Model Explorer Filter Bar which displays only the objects currently assigned to the searched schema.
See the image below for an example.
It is a good workaround.
