'need to avoid writing directly into columns that already have a value defined at the top' - what do you mean by that? Do you mean rows without any value, so creating new rows at all? Because if I 'write to a new table', the green triangles appear, and if I import a CSV with the same column structure (i.e., I don't create any new columns or rows, I remap eg company name goes to company name; no new rows), then the green triangles also appear. So I don't know what you mean. Do you mean if I create completely new rows?
And as I said, the reason I don't want to have those three green triangles is that they are super easy to reset or revert the whole data, and there is no chance or option to actually see the history of a cell like in Google Spreadsheets. I don't want to end up in this situation where I have a value and I click on this "revert back" and the whole data is then lost. In my opinion, it's a very bad UX. What's the reason? You can make an alert or so, but it's just hindering it's not good in my opinion. Make it better or okay, I see it and I neglect it. I don't want to see it anymore, but I have seen it.
