&zbiggestprocess Calling it there for the jam. Added peak memory usage stat. Overlay always displays the process with the biggest working memory set. I ended up not implementing the system tray, so with all unnecessary code removed the program is less than 100 lines of code.
I thought about always showing the process with the highest historical peak memory usage, but that always was a process called Memory Compression (must be some windows internal thing), so not very useful. Overall I'm surprised by how much I learned and how fun this little program was to make. Goes to show that even small contributions to jams can be quite rewarding.
