Four files at a time for Free Version

(I've only had the free version of this app for a couple of days) I'm a student and I needed something I can annotate with since a lot of my readings are online--something really basic really. I decided to get this app after a review I saw on the internet. In the beginning I liked it, it did what I was looking for. But after after trying to download more of my readings I noticed it was only allowing me to view 4 total. I kept having to delete one of the four files I already had in order to be able to open and annotate a new file. So if you're looking for an app to annotate your PDFs with this'll do the trick but if you're planning to stick with the free version know that you'll only be able to view/annotate 4 at a time.

All I really use is the highlighting in this app but the other tools it includes are useful and neat, I just really wish it would let me view more than four files!

A Few Issues but I Still Love It

I've used this program to take notes during class for the last three years of Graduate School. I absolutely love it! The few issues I've encountered is not being able to save the different highlighter colors I like to use. There are many ugly colors already programmed into the app but you can only select 1 unique color at a time. If you want to switch to another unique color, there is not a way to save the last unique color you liked/were using. I would love to see that fixed

This program was recommended to me by tech advisors and faculty colleagues at my university. I downloaded the Lite version on my iPad Pro. When attempting to connect to my university Box account, it crashed (but my Box App works fine by itself). When accidentally opening a new dcoument, you cannot leave it unless you save it. Once you leave it, I cannot find any way to delete it, there is a Trash tab, but no dragging or tapping or multi-tapping or menu-exploration has led me to a way to delete a document. After a while, because I kept getting annoying pop-ups recommending that I buy the $6.99 upgrade, I relented. I spend the money, but all the problems remain. I also thought that the $6.99 “upgrade” would get me DocAS (without the “Lite”) but that was not the case. Given how strongly recommended this app was by professionals at my work, I can only guess that this might be related to using an iPad Pro, maybe.
