Add a single-command function to create new layers for all pages in the same pdf file
ask for one single command to create new layer(s) on all pages for note taking purposes. easy to toggle between showing and hiding the notes.
Now users can only create new layer page by page by "importing layers" from files. Adobe should bring in the similar function available in Photoshop which allow users to create a blank layer(s) for all pages of a pdf file in a single command, and let users to enter notes, comments or other annotations on the selected layers. readers can then switch the layer between visible and hiding depending on the use scenario.
