Two new ePub editors have come to life (or rather one, since they obviously are the same software under different names and version-numbers

:
Coolmuster SignPub:
http://www.coolmuster.com/signpub.html
and
iStonsoft ePub Editor Pro:
http://www.istonsoft.com/epub-editor.html#
I've tried them both (for about ten minutes

) and find them lacking things as spellcheck, filesplitting, sourcecode editing etc., which we are used to in Sigil and the Calibre Editor. Given that, I find the price tags of $ 49.95 and $ 35.95 a wee bit stiff.
Also, I have previously mentioned the Fosfor ePub editor
https://blogs.oracle.com/geertjan/en...b_open_toolbox, but sadly the programmer doesn't seem to do any work on it (Despite his claims to the opposite, nothing has been done for around 9 months).
I stumbled upon this
http://www.epubgen.com/software some time last year, but there doesn't seem to be a real, downloable piece of software to download, despite the nice pictures ... strange ...
