I'm testing Cosmic Everyday on a real Ubuntu 16 machine. For now, it has the following platform-specific issues:
- Sometimes it requires a key/password for encoding its database or so. But it shouldn't.
- Sometimes auto-launch can't be set up correctly. It is mainly dependent on the distro type. Cosmic Everyday might tell that auto-launch is active when it isn't, and vice versa.
If you close the window, you will be able to reopen it with global hotkey only (ctrl + shift + e), but not via tray icon.(solved)
Please report here if you see something unexpented that is not included in this list.
