What is the feature or ability you would like to have?
In the track manager have the option to remove the album art.
How will this feature help you and others?
Currently a number of tracks, can have cover art, but it seems like there is no option to remove the album art.
Is this feature available in an existing product? If so, what product?
In iTunes, Traktor Pro, Rekordbox
Does a workaround currently exist?
I remove the cover art via Rekordbox or Traktor, while playing.
Bulk editing/removing of cover art is on the ideas list for later. Definitely something I will be adding.
Nice to hear about the bulk/edit is on the idea list.
Is the option to remove the art work from a single track already available?
Side-question, is there a way to contribute to the software?
I’m active in opensource projects and depending on the tech stack, I could create PR’s to facilitate minor features.
No, there’s no edit or removing artwork at all yet. I use Tagscanner (windows) to bulk remove images when I need to.
What kind of tech do you use? I do all the tech alone right now (kind of prefer it like that) but there are a few areas that a bit out of my comfort zone so anything is possible there.
I also use Tagscanner (via Wine) on Mac.
It is one of the best MP3 tag management tools.
With regard to tech, I know my way around in NodeJS/PHP.
In what tech is Lexicon build?
Electron, typescript, python and some more things. At the moment I don’t really need help, but might change in the future. Things like machine learning is challenging 
Keep up the good work, since Lexicon is an impressive tool.
It solved so much of my Traktor to Rekordbox migration troubles.
