Hi,
I think I understand your question, so I'll try to answer it,
Someone thought to add the Italian language to the ESXi object GUI, too bad they did it in a way neither complete nor accurate and basing the selection on "cookies" and with preference to the "browser default", thus whenever the "cookies" are deleted you find yourself with the GUI of ESXi objects in "Italian" and the GUI of many other products in "English". Translating the label "free" intended as "free disk space" in "gratuito" or "libera" or translating the label "Number of displays" as "Numero di visualizzazioni" it does not make sense, it would have been enough to involve some of your native Italian-speaking colleagues to take a look at it before introducing this functionality.
I have noticed that in the most recent versions of the ESXi / vCenter product here and there "some color detail" and "visual effect" have been added, but no one seems to have noticed that in certain menus the contents are presented in light gray on a white background that is difficult to read or that certain fields would "appear" pre-populated while they are not at all (they are "blank") and this in some cases is a source of confusion.
We could also discuss those reported "error" that are so generic as to be of no practical use, like "a parameter is not valid without specifying which" and therefore, to understand something I have to read several LOGs. And what to say about the most recent version of the vCenter object, if you want to edit the network settings you have to use "firefox" otherwise with latest EDGE / Chrome a "black box" is presented.
These are all things that for better or for worse have been discussed in this same forum.
Having said that and from my humble point of view, without any polemical intent, it would not be better to remedy the "differences", "inconsistencies" and defects" that you already know and then evaluating with your customer how much this contributes to the improvement of the user experience?
Regards,
Ferdinando
