Comment 3 for bug 1956392

I tested the auto-complete popup in https://github.com/mixxxdj/mixxx/pull/4505 and it does indeed improve the workflow. Right now it's styled by the system theme which is absolutey confusing. As soon as I work out how to use a dedicated QStyleDelegate we can add it back.

An option in Preferences > Library to turn off auto-completion entirely is also no big deal IMO (default: on), as well as a Clear History button

Search queries can already be removed one by one from the popup with Backspace and Del in 2.4 alpha.
