PDF Overlay with Transparency
Please add a way to overlay two PDF sheets for comparison/mapping.
By default PDF backgrounds are clear - can we get a way to overlay the line information from one PDF sheet on to another? This would be extremely useful for architects, engineers, contractors, fabricators, etc.
For example, in Bluebeam I can take a snapshot anywhere in a PDF and paste it on to another sheet with no white background.
One way to accomplish this would be with a layer system. Another would be with the option to do an overlay sheet on top of another sheet, with the upper sheet having some adjustable opacity.

The topics below discuss problems like layers, transparency, locking, merging, grouping, object order, visibility, and rearranging—issues that would be solved if GoodNotes added a new layers feature.
If everyone supports the most popular topic, we could total 3,150 votes for layers! By uniting, we improve our chances of getting this much-needed feature. With GoodNotes actively working on a beta and releasing important updates, now is the perfect time to vote.

Firstly, Thank you @Brooke for taking the time to gather and post all the threads of similar nature. I’m voting on them all!
The issue for me:
Text boxes (that have to be placed and then annotated) often shift while using gestures; which cause annotations, such as highlighted text, to be in the wrong places. Not only is it annoying but if it’s not caught straight away, can be problematic. Layers or the ability to lock items in place would solve this.I ought to mention that having a text box deselected from the lasso tool does not always work. If I tap on the text box alone, I can still move it.
