An update a few months ago broke navigating in the outline sidebar. It's frustrating that they're focused on adding more and more esoteric features rather than basic functionality they broke in earlier updates.

I use this PDF app almost exclusively. It really is a vital part of my work flow. After the update to 3.10 I noticed that the Enhance Scan toolbar doesn't stay open after save and close winodw. In my case I'm using this to remove distortion from scanned music. So I might have a full 30 parts that I need to remove the distortion on, but there's no "batch process" function. The apps tool bar menu used to stay open after closing a window or file, but now it doesn't so I have to add quite a few clicks to process all the files I have open. Please, a "batch" function would be great!

Lacks a simple form filling process

I have loved and relied on this app for over 3 years now. I use it on both my ipad and mac. Measurement coming to Mac is a blessing. Thank you!!!!!!!!!

If they added features for multiple page signing/stamping and one button flatten - then this program would be perfect.

I have greatly valued this app. The ease of access to tools like blackout, rotate, and delete pages has made it much easier for me to store work documents. Easy interface and seamless performance.

I want to publicly thank the team for adding measurement tools into the desktop version. As a construction project manager, this is the best addition that I could have asked for. In fact I did ask for it several times and the team responded!! You rock!

managing pdf's for research projects can get messy. One of things that has saved me so much time is using this app. I get a free "popular" app through my job, but I hate the interface and constant issues siging into other devices. This app has a great interface and helps me track my highlights/notes when I write my papers. Are the highlights better than the other key program? Not really better, but it is just a better reading experience on this app, no question. I recomend this to my new doctoral students to help them find a way to manage a lit review. The thing I appreciate most is that it easily fits into my work flow.

This is well worth the money yet far cheaper than Adobe.

BEST PDF APPLICATION. INCREDIBLY THE CONTINUE TO IMPROVE IT.
