It is impossible to reach the settings menu of the Seafile Client if the icon is not visible in the task bar. This happens most often in Linux systems after hibernate but also sometimes while using Windows and Mac.
Also the options menu should be available in general via the client main window and not just via the task bar icon. We have many users who are searching for the options but never even considered to check the task bar icon with a right click. So it’s also a usability issue.
Please add the options also to the main window via the commonly used three horizontal lines for options.
Here is an example from Firefox.
The options menu could be in the top right corner next to the refresh icon.
