Very nice tool. Unfortunately last comatibility with 35.x.x thunderbird. Is it in plan write new version for 38.0.1 ?
I know, mozilla (and firefox) team make big mistake, followin hurry uping with numbering revisions. Why internal interfaces aren't versioned? addons are (in)compatible with internal interfaces, not with all thunderbird.
Why numbering doesn't follow major/minor versioning?
first number, copletly new version what optionally follows compatibility with specified previos version,subversion. second number, it is some minor improvements, with all backward compatibilities with this major version. second subversion is only ad-hoc security/stability fixes. Why it is NOT supported by mozilla similar to old supporting school ?
