Not a major issue, but it might make sense to switch to the MSEdge-based WebView2 instead of CEF if CEF-specific features aren't used. It appears SyncTrayzor currently includes its own copy of CEF in its installation package, taking up about 250MB of disk space. WebView2 is preinstalled and automatically updated on most modern versions of Windows and the WebView2 files can be shared among applications, saving disk space.
