This is just a heads up. (And I hope I'm not stepping out of line.)
I don't know where in the development cycle any new OS gets built against,
but the preview panel doesn't render correctly with macOS 26 (beta 3).
Text is rendered as a question mark inside a box. (attached)
(and to further the discussion of icons on the mac, they changed the look yet again.)
Cheers and thanks for the good work.
