I wanted to make some text smaller and I went into the edit text mode. I clicked on the down arrow to make my text smaller and the entire panel disappeared. I had to get out of edit mode to check my font size (which did reduce by one size) to be able to see what changes I had made. I needed to go smaller so every time I tried to make a font size change the panel just goes away.
I haven't found all the new changes yet but RSD really is a lot faster when saving a file and loading a file.
