I don't know how pathetic this sounds, or how awkward it would be to implement, but would it be possible to have a visible completion percentage on or next to the progress bars?
I'd find it infinitely helpful if I could see a completion percentage when ripping because if and when an inevitable failure occurs I always retry several times from the same or different drives, and would love to be able to see if any of the different attempts make better/worse progress. I'd also have a better awareness of just how quickly the attempt is progressing.
It's all well and good seeing source file size (which definitely will contain parts of the track that I have deselected) or looking at how big the file is at the point of failure, but sometimes I try different things (like not deselecting all the audio or subtitle tracks, selecting different combinations, etc).
I just think it would be a minor QOL change that would be really useful when troubleshooting problem discs and getting an overall sense of true progress, vs having a bit of a guess at how long the green line on my screen has gotten from the last time I looked.
If this is a stupid ask, or one of those things that way more complicated than it's worth, I apologise in advance.
