Worked on JerOS today. Calculator history moved to sidebar, now shows full expression. Fixed duplicate heading bug. File manager now shows actual files when clicking folders. Terminal prompt switches between green and dark gray based on theme. Desktop icons bigger with better text visibility. System tray functional network, battery, volume all working. Taskbar right click menu opens task manager and settings properly. Added wallpaper upload, keyboard shortcuts, font size options. Light mode fully fixed. Feels more polished now.
