It is not kindness, it is the official calibre terminology.
And you should understand, that the Conversion feature is under no circumstances
meant to be used as input for editing -- it was designed as a way to ensure consistency of design while papering over various device flaws, for the sake of end users who don't know what a file is.
Why on earth are you performing a conversion just to merge the internal HTML files?
For that matter, why on earth would performing inter-format conversions for the sake of merging the HTML files make it easier anyway??? Why is "one large HTML file" a desirable objective?
Since the
real problem* you have is "I want to reformat the whole EPUB", I have a better solution for you.
Open the EPUB in the E-Book Editor (shortcut key is "T"), and reformat however you like. If you want to use regular expressions, you can do those on the
whole set of files. If you really, really, really want to turn everything into one unwieldy file, though, you can do that too, using the "Merge Selected Files" right-click option in the Files Browser.
* -- it is common for people to ask questions based on their
assumed solution, rather than ask questions based on their
underlying problem. Which is backwards.
