The intricacies of weaving through browser and google app to use this plugin are quite noteworthy. I consider it a great achievement that the plugin seems to work, even when it encounters strange circumstances. For all that this is a bit ungainly, there were some things I wished worked a little better, but overall quite good.

Can be a simple way to fill out documents.
I can fill out a document pretty fast. Its functions are easy to understand. Overall it is easy and anyone can use it even if they are not tech savvy.
I don't like how I can't control the fonts and the font size. It automatically selects the font size and sometimes it can not be changed.

Good product with a few minor changes
You need to be able to increase font size on just one word or 1 line, not the whole document. Also ther should be a notice when you have come to your margin so you don't keep typing and have to redo. But all in all it worked as it said and did a good job for me.I will use this again, many times. Thank you

What is a Digital Certificate and How can I View it?
The usage of a digital certificate is a kind of authentication to keep track of all changes made in PDF files. It comes into action after the complete document is signed by the last authorized certifier.
In case the changes were made after signing the document, it will invalidate the digital certificate.
To view the certificate, one needs to open the document with Adobe Acrobat Reader. The certificate will be seen under the signature panel. By clicking on this link one will see all additional details about the signer and document itself.
