Why does my Opus 10 (and 11) show non-informative compression progress windows (for any compression format)? I've seen somewhere on screenshots it normally shows more info such as elapsed time, ETA (and maybe even compression ratio).
For reasons too complicated to explain. 
It's on our list but not a huge priority, since it will require some fiddly work & re-testing.
I will gladly pay for your "fiddly work" by buying Opus 11 & can help with "re-testing" (have 100% repro non-stop)
I find ETA & compression ratios very much needed and very much missing when compressing via Opus (which is most of the time)...
