The only way I know of to ensure the cover remains at its large size, is to extract the cover from the ePub and make it your calibre cover. In which case using the update metadata command of the plugin is going to not negatively impact your cover at all since it will replace it with the same one.

In that case, I did understand the way the plugin works.

In my opinion there is a big advantage if you should provide the option as separated functions.
You've created a plugin that can change parts of the content of an epub without editing other files.
E.g. if I use the calibre explode and repack function, or use sigil, they all change additional files. e.g. files not in the opf are removed. This is not always what you want.
In my case, I often want to change just some info. E.g. a lot of files do have the author swapped (ln, fn) or have the language set to UND (or worse, EN while it's not).
In that case, this is the only info I want to update. At this moment I unpack the file, change the data in the opf and repack the file (not with use of calibre because of the additional changes).
In my opinion it would be great to skip this part and just use the plugin to update the data.
imaginary workflow:
Import epub in calibre (including available metadata)
Edit metadata in metadata window (e.g. swap ln, fn and change lang)
Update metadata using the plugin (cover is not touched).
This way, I keep most of the original data and only change some info or add some info (lang, pubdate, ....)
While I do not need to convert the file, there are no other changes made, it is the fastest way I can think of to update or change some metadata without loosing or changing other files.
I was thinking this was one of the main purposes of this plugin (But it seems not to be, I'll have to hack it
).
