The workflow of Issue working may have some order. For example PM post new issues to project and want to see it in project plan. We need now use follow workaround. First we separate project by versions as project stages. We post issue and set "Fix for Version", and choose version for planed fixing issue. To ordering in versions we using priority. In result we have roadmap: 1.0.1 Issue 01 Issue 02 1.0.2 Issue 03 Issue 04 1.0.3 Issue 05 Issue 06 1.0.4 Issue 07 Issue 08 But we need follow: Issue must have link to depended issues (how we use for it link "Depends", we linking depended issues but it not affected on issues ordering in Road Map). In Road Map, firstly show independed issues, follow its depends indended by space. The road map must look like a tree. For example: Road Map: 1.0.1 Issue 01 Issue 02 Issue 03 Issue 04 Issue 05 Issue 06 Issue 07 1.0.2 Issue 08 Issue 09 Issue 10 Issues in one level will ordered as now in roadmap - by priority. Thanks!
