Based on the content of the document, you may want to create a feature directly from that document. To do this:
Select the content out of which you want to create a feature. A toolbar will appear near the selected content.
Click on the 'Create feature' button.
A side tray for feature creation will open up, with the selected content as part of the description for that feature.
Add the required details and click on the 'Create feature' CTA.
This creates a new feature in the workspace and is automatically aligned to the document from which it was created.
The created feature will be displayed in the 'Aligned features' list.
