Orion Viewer Customer Insights

1. Auto crop chooses 1 pages at random to be good with and you can't manually adjust any of the pages alone--so you're praying the one it does pick isn't garbageGood progress being made with this app, and an up-to-date PDF + DJVU reader with issue-free external storage access is sorely needed.

2. Kudos to the dev!It would be good if it did not lack text selection… Viewing a document without being able to copy a certain piece of text is just like watching a movie when you are both blind and deaf.Larger than Document Viewer and somewhat slower.

3. I would rather use online converters to convert the file into pdf format which is very easy to open and read.I downloaded this to crop pages.

4. You just can't see the next pages (at least it was only showing me 1 page only at a time), you MUST turn pages by inserting page number.

5. This tool does what it has to do very well.no support for external storage like usb or google drive.Unable to open any djvu files.

6. The one to treat even pages might as well not work because it produces random behavior.

7. I read quite a bit and i disliked the app.till now best pdf viewer without any full network access permission.

8. ALL pages must be done together.

9. Thanks.Don't mind them all and keep doing the great job.

10. At least there is no spam in this app.Could not get the app to work in any organized way.

11. This fits the bill.
