Everything related with SP Doc Kit, from installation process through configuration changes or even troubleshooting issues that arise during its use. The support team at SpDockit are excellent (especially in Spanish) as well, so if there's anything you need assistance with it will be fast resolved. I can see myself using this product daily and solving my problems instantly without having to ask anyone else! If someone has an issue they usually know how to fix them themselves but sometimes when you have some minor things that may not make sense immediately but still needs resolving, such as configuring your document library layout etc - then asking questions here won't hurt either. There isn't really anything specific; everything works great. Just as long as you're comfortable working with computers/networks, Spdoc kit should do just fine. This allows me to be more efficient in our office because I'm able to get all of my jobs done in less amount of time compared to what would normally take hours.
