Seeing the contrast of users count between Calibre and Sigil, and the complaints and debates here, I really worried about the future of Sigil.

I am thinking if Sigil should start as a commercial software instead of a freeware as Calibre. The reason is that Sigil is for a minor user groups but professional than common users like those of Calibre.
Comparing to readers who need a converter, Sigil or an ebook composer users generally,
1 are more professional.
2 need more professional functions, better performance and extreme robustness.
3 use Sigil much more frequently than a converter.

But comparing to Calibre, Sigil is more difficult to develop and improve. Such as the Book view is a small version of MS Word, and Code view is more than an text editor. As least, a Sigil is no less than a Dreamweaver.
So, depending on a few/or even one or two genius on theri spare time is not enough for such a huge work.

So I'm thinking if commercial way can make Sigil better and better, at least, a steady revenue can support its development and improvement.

In my personal opinion, free mode is not fit for Sigil.
Here, I hope all who concern Sigil would express your opinions, no matter pro or cons.
Thanks.
