Hello!
I found some issue with 2 new buttons you've added in v4.1 instead of the old ones.
When you transfering files and press on the "Pause" or "Start" buttons - you can't know which one of them is selected because their colors are gray when they Active and where they not.
Here is screenshot that may help you understand this issue:
It's will be great if you'll change the color for the Active button.
Thanks!
