Request for Silent Startup on Boot

Due to my specific needs, I need to set Simplenote to launch automatically at startup and run in the background. However, whenever I set Simplenote as a startup app, a window always pops up no matter what. This forces me to manually close the window every time I start my computer, which feels quite inconvenient.

I would like to request a "silent startup" feature. Ideally, this feature would allow the app to start automatically without displaying its window, while still keeping sync and notification functions active. The app window would only appear when I manually open the software.

The issue names no files, tests, or entry points. Start by locating the TypeScript/Electron startup behavior and checking how automatic launch, window visibility, sync, and notifications are handled. Done means the app can start in the background with sync and notifications active, showing its window only when manually opened.
