Nebo's latest beta feature makes the scratch-erase gesture available in import PDFs as well as freeform pages and sections.
You can scratch-erase with your pen to swiftly delete the content from PDFs as well as freeform pages and sections. When deleting shapes, be sure to scratch over the edges so that Nebo knows you're not filling them.
Scratch-erase in freeform and PDF is available to users as part of the Insider program, which is accessible to users on Nebo iPad only. The feature can be enabled or disabled via Settings > Insider program.
Note: Scratch-erase in freeform and PDF is auto-enabled for users who previously agreed to contribute to making Nebo the best it can be.
