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

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 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.

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

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.

Can you add connectivity to Box to grab files, much in the way you have it for Google Drive and Dropbox now?

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.

I would like to be able to turn off the auto-save option when opening pdf files. Sometimes you don't want to save the pdf but just open it.

Would be nice if i can read djvu books with this smooth and great app for annotations.

the iannotate app has a feature that allows users to make user-centered stamps (such as checkmark or whatever with the drawing function) and store them in the tool bar for repeat use. This is AWESOME for grading papers! Please consider this functionality. GREAT APP! thank you soo much!

Ability to set a default folder to view rather than always starting in the default storage location (sdcard, etc)

The cropping is good, but after automatic cropping, some pages are narrower than others because of different margin size which is fine,
but please make it so that after cropping, each page will be automatically adjusted to fit screen width.
