Just a usability issue. Reproducible: Always Steps to Reproduce: 1. Open Settings -> Plugins; select Configure button for Lame MP3 Encoder 2. Switch to Advanced tab Actual Results: The Encoder Quality is set by a spinbox, but there are labels underneath ("fast encoding" / "high quality") on opposite sides. Expected Results: Either the labels would be removed, since there is no mapping between them and the value in a spinbox, or the spinbox would be replaced with a slider as with the Quality Settings slider/labels in the main (Settings) tab of the dialog.

Yep, there is code to enable the slider, but it is used wrong. Easy to fix, marking as a junior-job.

Thanks Jeffery. Please understand that k3b currently has no maintainer, so that no official release is to be expected to include your fix, unless someone steps up volunteering.
