Support S-pen (or other pointing device) to switch annotation type or switch annotation/selection or switch color.

... so we can, for instance, compare two pdfs side-by-side

It is natural to rest the palm on the paper/device/surface while writing with a pen...Currently we can't properly write because our hands' palms interrupt the pen input. Please add palm rejection / palm recognition !

The default display mode when the device is in landscape position should be Fit to page width, not Fit to page height, as it stands now. (I don't know for small devices, but at least for tablets with high resolution.)

In other words, let the fixed zoom to the desired percentage.Could have an option to lock the zoom. For example, I want to lock the zoom at 100%, so I would like to read the entire file without modifying zoom. To lock or unlock the zoom could be used a padlock in the bottom-right corner for this option.
Then clicking on the padlock, lock the zoom (100% or 90% ...), clicking again unlocks.
Several times I am reading a file and it approaches 300%, so I have to keep adjusting every time it happens 150%.

I would very much like a LInux version of your app. I work on several different platforms and it is frustrating to use one program for one platform and another for another.

I do a lot of handwritten notes at the sides of pdf docs. It would be a more natural experience if psi was supported like in one note.

Hi, I would like to suggest this feature where when I search for a keyword, a list of results would show in one page along with details such as chapter, title, page number or even a small thumbnail. This would be easier to search in big files such as manuals and so on. Really appreciate it if you could look into this as I've found the best app for PDF for iOS now. Recommending to friends

Please make the iOS app fully integrated with Google Drive. Please make pdfs editable once they are opened in Drive. Our students are depending on you. THanks tons, Eileen

Now that we can take notes directly with the stylus, he have no way to group several strokes as one annotation.

f.e. if I need to move a whole paragraph, have a tool that lets me select all the text I want to move.

I like your app and use it in my tablet. It would be nice is you can build a windows (desktop) app. I don't like to use the metro mode in my PC.

I like to show all the PDF in a Bookshelf like Interface with cover page (eg: IOS.iBook) instead of Recent view.

A great option to read in reflow text so the user could read with larger fonts or while reading a pdf with 2 columns.

Annotation option while reading the reflow text can make research easier.

I am using android Xodo. When exiting the app, usually it saves the cloud files automatically, but sometime it does not. Please add a "Save" button to allow manually saving cloud files, or add a feature to remind users to save files when exiting. That way we can make sure we won't lost our work.

it would be good if there was a note with sound

Use "swiping" to switch between different pdf's that are in the current folder. If you are working in a folder with 10 pdf's. It would be nice if you could switch from file 1 to file 2 just by swiping to the left. This way the productivity would increase further.

It is convenient to just pinch to make a page smaller and further pinch to get an overview of all pages as thumbnails. Please consider implementing this productivity sensitiv feature.

You do a great job.
