Hi Paul,
Most people doesn't mean all of your clients will do the same thing, right? Maybe those clients that you are talking doesn't have a clue what Google Fonts API is all about, but you guys have already added a clear description and where to go to create the API. Well, maybe you guys have to clarify that in the documentation and if there are those doesn't read and have no clue just point them to the documentation. My point is, just because of those who doesn't have a clue or doesn't read, your decision making in adding cool features gets affected. Instead of making your product better, you'll make it more friendly to those slacker.
As for SPPB Google Fonts, I think you haven't use it for a while. Try to compare the fonts in Google Fonts and in the add-onn Font Family dropdown lists, it is not so current. For example, fonts like Cherish, Ephesis to name a few. As for "not needed feature" :D I guess I don't agree with you. The principle of how Joomla was built is really awesome! They made it so configurable like providing template overrides and that makes it so powerful. You guys made SPPB and HelixUltimate configurable also by providing overrides, that means you guys saw the power of giving people choice. So, my point is, in your personal opinion "it is not needed feature", it doesn't mean it is not also needed for other people, right?
This is also my personal opinion, but your agreement will probably affect our decision making in using your product in the long run. So far, I just like SPPB and HelixUltimate and that's why I am building our next website on it. I want it to be much better and feature rich in the future.
By the way Paul, what's K2? :P
Thanks,
Jackson
