On July 24, the DesignScript team provided me with an update of the technology preview. This update is build 0.6.46.9306 and includes defect corrections based on your feedback:

You can check out the new release for yourself via the Autodesk Labs site:

• Node previews for simple literal values (e.g. "10") are no longer shown.
• Node previews can now be toggled globally with a single menu option.
• Performance surrounding node selection has been greatly enhanced.
• Performance of node rendering has been improved.
• Comments are supported in Code Block node, so a code block with comment can serve as comment node for the moment.
• DesignScript Studio documentation link is added and can be found under Help>Introduction to Studio
• Improved support for Replication guides.
• Improved error handling for the import .ds file.
• Events Support: Property changed notification events from external library can be used to trigger update in DesignScript when an object property has changed
