Most people without a computer science degree aren't going to know what "Context path" means. Worse, on a TV monitor 10 feet from the couch, "Context path" looks a lot like "Content path" - or the path to all my music. I just wasted about 45 minutes with this, trying to get this field to point to G:\iTunes. So here's my suggestion...
If it's a setting most normal human beings will never need to touch, tuck it away in something like "Advanced Settings." Furthermore, add some tool tips or brief descriptors of each field in the control panel UI. Something like "The field does yada yada yada. Most people won't need to touch it." This would save a lot of time for novices like me.
Thanks.
