Squid is able to create new Note from an existing PDF file. However the PDF generated Note is not a first class citizen. I need the ability to correct/delete parts of the PDF generated Note.
Rational:
I am a teacher and use digital ink to present my classes. The notes are highly technical engineering equations and or diagrams.
I have several years of lectures notes written in another app. Those Notes are living Notes meaning I need to revise them periodically. I am interested in moving to Squid. Squid will import my PDF ok but will not allow me to make corrections (delete part of note and write a new equation). I can write new text but I can not delete the wrong text. Thank you.

I agree! I would like to copy formulas from a Pdf and paste it to a notes page

Me gustaría que la aplicación tuviera la posibilidad de poder borrar y suprimir parte del pdf exportado.

My problem is this. I would like to move to Squid. But I have handwritten notes in another lecture program. I want to know if I export my data as pdf from my current program, and import it to Squid, will it be in Squid treated as regular Squid note with ability to delete and write more on the original lecture notes. If I can't do that I am not moving to Squid. If anyone from Squid actually read this and/or if something is not clear please contact me by email. --cheers

It can be better to add a inside clipper feature. After adding PDF or sth else, we want to cut out a specific parti of it and, we want to re-shape, either enlarging or the opposite. Or we want to place the part to another side of the sheet.

It would be nice to be able to export more than one site out of a pdf, for example when you only need for example chapter x of something.

Also it would be quite nice to copy and paste pieces of an imported pdf and paste it to another position.
I currently have to make a screenshot and crop it.
