Yeah, for feature requests/general feedback you can send those straight to support@axure.com, which ensures that they’re seen and passed to the product team since that’s the support team’s primary channel. Feel free to also send any urgent or confidential issues that way as well, and bugs!
As far as how to simulate hovering rows, this should be doable within Axure RP if you leverage mouseover interaction styles or the Mouse Enter interaction to trigger mouseover fill colors or selected states on the repeater row’s background fill widget.
That said, it looks like the Mouse Enter/mouseover triggers aren’t working correctly at the moment (they require a click) so I’ll file a ticket for QA to take a look, but it looks like the javascript solution above does the trick for you!
