Currently the longest duration per image you can set for the slideshow is 60 seconds. Could this be increased? It still feels quite short to me. Thanks :)

You can extend most settings by clicking on the number, then setting it to something higher, For instance, If I put my Strength Multiplier to 200 the max, The visualizer doesn't move all that much but if I set that baby to 3000 she gets jumpin. >:D

Thank you for this comment! Saved me a lot of pain.
