overall I like pdffiller, but there are some things I wish I could do, like circle items in word docs. The only circle function I see does not seem to work very well. I would like to be able to draw circles around items more easily. As for signature authentication, is it necessary to include date? It would be easier if the authentication did not include the date. This isn't a big deal, since I can see why the date is necessary... but sometimes I sign a contract on for example, Sept 1st at midnight, but I don't want my clients to know I signed at midnight Sept 1st, particularly if I should have signed the document sooner. Anyway, these are just little issues that I've come across and changes would make my business a bit easier.
