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 !

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.

the ability to add photo as an icon that will be enlarged when pressed to reavel the full photo. Similar to the way adding notes is currently working.
or better off improving current popup notes by making them support handwriting and photos.

annotation toolbar always visible, we sometimes need it to be hidden while keep annotating with a certain tool.

add a search box to search/filter bookmarks/outlines only (not the whole PDF file) , this will help to navigate large textbooks to quickly jump into a specific subject when searching reference (medical) books.

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

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 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 nice if we had the ability to recognize text in a PDF so we could use the commenting tools properly. I currently use adobe to recognize text and then upload to Google drive to use in Xodo.

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

I want to be able to crop an annotation that I add (like a photo or a digital sticker). I want to have both a rectangular crop and a free hand crop option!

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

Most styluses have an eraser on the rear end. It would be nice if using the eraser would actually erase (a) either whole notes or (b) just parts of pen strokes, without manually selecting the eraser tool by just flipping the stylus over.

Sometimes my notes dont fit in the margin space of my documents but I still want to see it without using the comment bubble. The option to rotate the text box so my note would fit sideways in the margin would be great.

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.

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.
