Simple and fast issue management system. Treenga helps project managers, UX designers and QA teams to create well-defined tasks/issues, easily organize them and track their completion. Shortly, Treenga is some kind of mix of Dropbox Paper and Github Issues, so a single task at a time interface with text+images task descriptions, along with category/people assignment features. Tasks are grouped by categories (tags), which can be hierarchical and represent your project structure.
