Audacious

If the indicators are visible is probably related to the theme / Qt version / desktop environment you are using.
I see them on my setup and they look similar to your example.

Ahh, okay, I see that there is a line being drawn underneath the actual cell you're hovering over. So part of what I suppose I'm asking is if that line could be extended across all columns. As it is, being able to see that line at all depends greatly on both where you've grabbed the row, and where you're hovering. It seems I tend to grab near the album name, and if I'm hovering over any of my first few columns, that underline is basically never (or at least very rarely) visible (see aud1.png). If I move it all the way over to the track names, then yeah, I can definitely see the line (see aud2.png). Alternatively, if I grab the row near the very front of the row (where I have the track number), it'd be more obvious, so I could certainly just start doing that, now that I know the line's there.

It'd be pretty nice, IMO, to have the line drawn across the whole row, though, and that's what the example does up there. As one more example based on that app of mine again, If I've grabbed on the "map name" but I'm hovering it over the "room count" column, I still get the position indicator clearly visible. (That's map.png)

Grabbing near the start of the row is certainly a perfectly acceptable workaround, of course, so I'm happy to just do that from now on. IMO it'd still be nice to extend it out, though. :)

Cheers!

Thanks for the insights. The attached patch is based on the solution from StackOverflow.

@John, Ariadne: Do we want to merge this? Does it look correctly on macOS?

I've applied this patch for 4.1. Thanks all!
