Very good piece of software, however since you changed the GUi, totally unusable for me :(
Because of sight issues i have difficulties seeing different shades in one eye, the new GUI colours are Grey on Grey, and because of my sight issues all i am seeing is literally a big grey rectangle, making it totally unusable for me unless i close my right eye, which is not something i would like to do all the time.
Please at least change it back to white text on black so i can actually see the buttons to use them.
