Hi Guus,
The Simple Answer is yes I'll take each question
- You can use the projects I.E. Project Version Button then double click the Project to add a project to the list this project can relate to whatever project company you wish by giving it a name that relates to both, I haven't Added a Clent/Customer to the projects but you could do that by adding the field and relation to the project table
As A Thought you could use the Time And Billing Template And add what you need from the bug tracker to that project, If there is enough interest I may do that myself - At present there is no reminder system I may create an example for one though but am very bussy at present
The Customer is Assigned on the new bug report screen As a contact report I did that to allow for both inhouse and client reports
The Employee can be assigned to each bg report so as to say whole is doing the works
