First of all I like the Bug Tracker it make it easier to report bugs and keep the overview over already reported issues.
But could you please add the possibility to add some "general" issues.
If you open an issue you need to append and ".stl" and ".zcode" file, but there are some issues which are more general and so you don't have any specific file for this.
I can assume that there are lot of other cases where you don't have any specific ".stl" or ".zcode" file like firmware issues or general feature requests.
Maybe the Bug Tracker could be splitted to the different parts like:
* Feature Request
