I really like the option to use indicators (connected to the connector pane) as the output for webservice methods. By default, Labview will serialize it to JSON, but text and xml are also options. It works quite well and it saves a lot of coding writing your own serialisation.
I have some suggestions for the serialize functionality:
1. order the JSON output by tabbing order when there are multiple output indicators. This prevents that you end up always clustering all controls into one, just to enforce order.
2. it would be nice if an enum could be represented by its string instead of its index.
3. support for maps
