First, the specifics:
Previous versions also had the waveform scrubber in the footer.
The arrows at the top haven’t changed. They are like your web browser back/fwd buttons.
Scrolling lyrics is new time code lyrics metadata … If we don’t have time code data, it doesnt sync but just shows the text.
Now, it seems you are clearly frustrated with what seems to you a total charge get in how the entire UI works. This is not the case, so can you help us understand the issue more clearly? Screenshots with comments about what feels wrote to you would be helpful.
The above comment unfortunately is not something we can take action on. I get that you are frustrated and needed to vent, but take a deep breath and help us figure out what you so clearly can see. Give us more to work with and we will do our best.
