Gwyple is a graphical frontend - implemented in PerlTK - for various bugtracking systems. It enables the user to handle bug reports from multiple sources in one consistent interface.
The gui consists of a listbox from which to select a bug report, and a text box that presents the content of the selected report. The listbox can be configured according to personal preferences and needs.
The appearance of the text box depends on the BTS backend. Usually it's just the plain text of the bug report as it came in.
