[FR] Show file name instead of the title in lists

[yezhiyi9670]

Is your feature request related to a problem? Please describe.

I do not specifically stick to some artists or albums, so I organize songs by prepending a unique number to the filename. However, to keep title clean, I do not include that number in the metadata.

In Gramophone, I have no way to see that number or sort the list according to it.

(This is also a problem for collections that are intended to be played in a particular order, indicated by the number in the filename)

Describe the solution you'd like

• An option to display filenames instead of titles in song lists (including the folder view, filesystem view and the current playing queue).
• An option to sort according to filenames in these places.

I woule prefer that the play controls UI still display the title (which does not include the number).

Describe alternatives you've considered

I could include the number in the metadata by using automation, but this approach requires technological knowledge and is not user- or mobile-friendly. Moreover, doing so will also change the title in the play controls UI, making it no longer aesthetically clean.
