@user_none: Hey, I've understood you the first time around and accept it. Your work is appreciated, you should not waste time on trivia.
All I do in Sigil is for my own itch/pursuits. Being an open source fanatic I propose useful and generic things upstream, trying to keep the book as I understand it. Others, I'll keep for myself or, if it works wonders (oh oh, it works!) in my world, I'll try to publish elsewhere - because I'm open source fanatic

.
And for more clarity:
1. After only about one year with C++/Qt I'm still not quite sure of myself most of the time.
2. Dry comments "because of designed" don't leave much space for discussion.
