Sorry for the late reply, but it's not true taht we wouldn't be interested. We are all trying to help users and to solve their problems, but in your case there were several reasons why you not got such a quick reaction from a user:
Most users in this forum are using the ESET software on the PC, so the Online Scanner won't be used and so we have not many knowlegde about it. Reproducing the problem can take much time. You formulate this not as a problem or "How to..." question, but rather as a suggestion. And because only someone from ESET can reply to a good suggestion in a useful way (like "We will implement it" / "The idea forwared to our developers") no other users wanted to reply to this.
So please don't blame us, we are doing this in our freetime (also the ESET moderators).
Remarks accepted, but "foneil" answered my question with impeccable clarity so the matter is closed.
