Yes, running external tools is on my internal wish list. I just counted your vote for it. Do you need any specific tool? Some are already available via Open with... from the File List's context menu.
The export function of the Windows version is a constant source of time-consuming support requests for me. While it might work for many users (I don’t collect telemetry, so I don't know any numbers), most of the people I hear from struggle with the technicalities of adjusting export configurations.
Based on that, I decided to take a simpler approach with the Mac version.
