• the script should only look for issues in commits that don't exist in theremote- users should be warned if an identical issue already exists (same user,same title)FIXME: Make it fully configurable- The user should be able to specify what prefixes to use for issues, notjust the string "FIXME" but arbitrary strings.- The user should be able to specify git branches in which issues aresearched.- The user should be able to assign issues by using simple syntax in thecode. Eg, by using trailing comments like assignee: username. Samewith milestones.FIXME: Multi-language support:- Depending on the extensions of the file, the script should be able topick up the right comment characters/strings.
