I've done a couple of styles on our testing site. Since I am not sure whether inheriting from Default Style would have any side effects later, so I've chosen NOT to pick a parent style, and I noticed it seemed always giving me the default style(before I make changes) anyway. Would that cause any problems when it comes to upgrades of the software? Before moving any further, I'd really like to get some ideas about the following questions: 1) When creating a new style, what are the benefits and possible problems of using the default style as a parent style? 2) What are the benefits and possible problems of creating new styles without a parent at all? Thanks anyone for sharing your insight about these!
