@SanneT - Thanks for the suggestion! Don't worry, we're planning on making more improvements to this popup. We wanted to push it since we felt it was better than what we had before, but we're still collecting feedback and usage stats and will continue tweaking things :)
Lingq is doing it's best. That window was well meant, and maybe for the newbies it's nice to see, but for us highly efficient, veteran lesson terminators it's two annoying clicks that slow us down by 3 secs.
