Needs a tad more polish.

The tools for manipulating PDF files are good and fast, though i would like to see better reading tools. Arrow keys dont work for navigating pages. Setting PDFelement as the default pdf application gives all pdf files a blank icon. Its a shame because when it chooses to open your files, its pretty fast. Following from the last point, I have to attempt to open pdfs multiple times, once to open the App - and then once more to open the file. This is very annoying,
