Why not implement a notes section similar to MS powerpoint where user can add their annotation to each PDF page in Adobe Reader or Adobe Acrobat to max profits, to max your salary increase to max charity donations for orphans? Please feedback to management.
Both suggestions don’t seem to add extra space to the PDF page (I’m assuming). If the PDF page have pre-existing full body of text, adding fields or comments to the A4 space will obstruct the pre-existing text. Assumptions.
On the comments part, I’m not too sure how it works, but I will investigate, I hope the comment boxes will be a separate space outside the A4 page which can be readable together with text on the A4 page with a single middle mice button scroll down.
After testing the comments feature, it’s little yellow pop up boxes which have its usefulness or can be missed though I’m sure there a keyboard shortcut to expand all comments, though the comments box blocked part of the text on the A4 page.
I felt IMHO that adding an extra app pane for notes taking will have its usefulness in certain limited scenarios.
