Hi! I have reviewed code of new classes (Database, WorkingCopy, LocalModsArea) Vlad, Why didn't you use verbs in some method's names? LocalModsArea.comments LocalModsArea.issues I prefer such names LocalModsArea.get_comments LocalModsArea.get_issues May be you should change names. What do you think? -- Oleg G.
