Is there anything in the Mac UI you found particularly glaring?

It's quite nitpick, so I don't want to sound mean!

Things like in the sidebar, the labels don't align with the selector boxes, and the 'gear cog' icon is non-standard. And when you click one of the disclosure titles, it highlights grey for a moment.

So nothing major, all fit and finish stuff that I guess is possibly a result of the app not being built with the standard macOS AppKit environment? (I'm not a programmer, so I guessing a bit.)
