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 !

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.

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.

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.

I'd love to see Xodo having a lasso and or box selection tool for moving around, deleting or resizing notes we took, picking apart drawings consisting of more small pieces is just painful.

I saw that Undo/Redo are implemented in the Android version but I cannot find them in the Windows version. Please add them with the CTRL-Z and CTRL-Y keyboard shortcut. Thank.

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.

Allow the Outline (that shows the PDF's bookmarks by default) to be edited, like Bookmarks. I would like it if I could add or delete the default bookmarks in Outline if I ever wanted to change them, as well as just edit (rename) the default chapter headings that are listed in Outline. Bookmarks already allows this, and it would be convenient for me if I could do the same in Outline.

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.

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.

It would be so perfect to have a small pop up dictionary like 'define' in ios.

As a language learner I have like 5 unknown words for every page and at the end of the article, taking a second look becomes an overwhelming task lol.

Still love XODO, thanks a lot.
