It does have good features, but it crashes too often and the bookmark option doesnt work properly, sometimes you can not add more than one bookmark which is not very convenient. Sometimes you can not read annotations made by a different software so i have to open the file in the preview provided by default on mac. Definitely it needs improvement and also would be great if we could be able to add photo anotations to the pdf, not only autoforms and text.
