Yes, that is another thing that is on the planned list. Ideally, some kind of data preview showing the skipped rows would be ideal. Generally speaking, it is better to open an Aeon Timeline 1 file directly in Aeon Timeline 2 rather than using export/import, as some data is lost in the translation. I will update the documentation on both counts.
Thanx...meanwhile, any chance of at least saying X of Y records imported...that would let the user know if something were amiss and needed closer (manual) inspection.
Once the dust settles on the initial release, this will be one of the first things I circle back around to.
