I often have to search for the folders. Colored folder will be easier to navigate.

Take my money, and build this...

I think Goodnotes should do away with categories like PDF outlines and Custom outlines. An outline is an outline irrespective of whether it came with the pdf or I created it. The outline that came with the pdf should be editable. And I should be able to create hierarchy in my own custom outlines.

Outline is one of the crucial feature in my opinion that sets Goodnotes apart from Notability. Please improve/complete this feature.

This is crucial for me. I need to be able to FULLY edit the outline of a pdf like pdfexpert does. Right now, to do the same (create sub outlines, for example), i need to export a pdf, use adobe acrobat pro to edit the outline, compress the pdf because Goodnotes exports horribly large pdfs, import the pdf back to Goodnotes and delete the original file... :-|

This feature will increase efficiency. I think a way to implement this would be using the lasso tool, if I draw a horizontal line across a page, then I will get an option to automatically send everything below that line to a new next page. This way, If I need to add new ideas later, I can simply draw a line and have the rest of the page to myself!

This is actually a great idea if implemented carefully. Google docs, ms word all have this feature. It is a life saver there, and so would it be here.

I would like to print just the pages i annotated in a book for later reference. Also, when i open an annotated textbook, i would like to know the pages i worked on.

I had a 14 mb pdf which became 84 mb after exportation! Insane!
