My job requires me to go through a lot of PDFs and have to always make notes in PDFs really quick. Anyone recommend a pdf editor/annotator that allows someone to draw/write on PDFs? I don't mind paid apps. Before, I was using a MacBook air and highlighting and typing text, it was quite the hassle and I thought a surface pro with stylus would be awesome! Especially with an eraser! The default "Reader" app is too buggy, sometimes I make notes and save, my drawings/notes become corrupt and blotch all over the PDF. Also it only lets me note in black so when a PDF has black text with black drawings/notes it is VERY VERY hard to read for others. I tried the following and here are my dislikes: Reader - dislikes noted above. Can't rely on making notes with it if it corrupts/garbles up my notes. Wasted hours. Foxit Mobile PDF - Does not have an erase function or undo function once something is drawn/noted on PDF, unusable. Note Anytime - Can't export as PDF and would be good if it supports the stylus eraser. PDF Touch - No eraser from stylus function. Once something is drawn and you draw something else later, the undo queue is cleared and you cannot clear previous notes anymore. Unusable. One Note 2013 - Zooming and editing and saving very cumbersome, have to import to one note, and then each page have to click a few times to zoom to fit page width, and then have to export back out as a PDF miraculously as one PDF with multiple pages. So much setup for each PDF I gave up. Right now I am using Word to convert the PDFs to make notes. But this is a bit silly too because once in "Ink" mode and you are making notes, your finger touches also make notes too so going to the next page with your finger requires you to deactivate the "Ink" mode first. Really annoying and just kills productivity. Anyone have any recommendations? Getting kind of desperate here and to be honest, frustrated this isn't even a default demand, considering surface pro was built for work.
