Locking VLC into a window size across files

OMG, I’ve been annoyed by this forever, never thought to see if there was a setting I could tweak... The issue: Watching multiple videos in a sequence (playlist), like, e.g., the free Eclipse and Java video tutorials. You resize the window and lay things out so you can follow along in the IDE, and take notes, comfortably; everything’s going great, and then the video ends, the next one starts, and VLC resizes the window to the native resolution of the video clip.

No more:

 

(At least as of 3.0.17.3, this is accessible via: VLC Media Player -> Preferences... -> Show All button, then expand Interface / Main Interfaces / macosx, and uncheck the box for “Resize interface to the native video size")
