I'm Brazilian and I use Adobe Acrobat Reader DC a lot. I'd like to suggest a functionality implementation present in PC, that I missed a lot on Android, that is "New window" or something like that, such as split the screen in two parts in order to see two different parts of the same file.
For smartphones its usage is restricted, but for tablets it can be really useful, because it allows the view of two distinct points of the same file,
I greatly reduced the use of paper by using this app, however, I need to navigate the file all the time to retake some points seen earlier, which causes a lot of discomfort when compared to printed material.
It is a suggestion, but I'd like it to be considered.
Thanks for your request. We have made a note of the same and shall try to incorporate it in one of our future releases.
