ebook shell as part of x2 portable

[science2003]

Just an inquiry on a possible integration.
With many ebooks, in epub and pdf format, I was particularly interested in your blog post "All ebook shell extension pack". The shell lets us see thumbnails and, with SumatraPDF as plugin (if I remember correctly), the ebooks can be previewed as well.

I know that x2 "ultimate" can be made portable. Would it be possible to include the above shell in the portability of x2 as well?

The question arises because I would refrain from "charging" Windows Explorer (and the Win 10 registry) for using thumbnails and previews: I fear in its slowdown. But I would be happy to have such a feature on x2 as a portable version when I need it, leaving registry and win explorer clean of such a feature.

all these shell extensions by nature require installation, so they cannot be used in a portable fashion
for portability you can use WDX plugins etc. You can check if there is one that does many ebooks

Thank you nikos for the prompt reply. With it, you gave me what I feared.

I asked because I noticed that in some portable versions there is a ".reg" file in the application's portable folder that it is used instead of the registry to keep all self contained. I was thinking - and hoping - of something similar.
