Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Fix desktop files Remove the "TrayIcon" category from the indicator autostart desktop file since it must be combined with "OnlyShowIn". Hide the indicator and preferences application in KDE by default since it comes with its own implementation. Display the preferences application in the Xfce system settings dialog.
