The oscilloscope node is pretty small, with the actual graph being smaller than the blank space of a regular node.

Shrinking the margins significantly would be an improvement, and giving the option to stretch the width especially would be very nice. Other analyzers also have large margins.
Dark mode would be nice.
I tend to use ctrl-shift-z for redo instead of ctrl y, but that causes an undo instead. Having both do the same thing would be good.
I re-export rather frequently. There are a lot of clicks involved:
Click the 3 dots, click project, click export, click one of the export again buttons, click start, click save, click yes
