Does Fossil-Scm have the ability to add new ticket statuses?

Yes.

The "status" field of the ticket table is a text field, so basically you can use whatever status you want.

You can change the list of statuses available in the dropdown mailing list:

• go to page Admin
  
  
• click tickets
  
  
• click Common
  
  .

On this page, you can edit the list status_choices

(among others). The order you specify here is the order in which the statuses are displayed in the dropdown. If you want to include a space inside the state, place it between the "double quotes".

When you're done editing, don't forget to press the button Apply Changes

.
