Just trying the 5.0 beta for the first time.
I like the new Consolas font.
The manifest editor is still a separate window. Why not just make it another tab in the code editor? I'm not sure if making it a separate window has any advantages, and it just seems out of place.
Also, the manifest editor ignores the font setting of the code editor. I increased the font setting to 14 in the code editor, but the manifest editor still shows the default size.
Hope this helps!
