MdcuCompanion

It allows you to easily browse series on Marvel.com with rich informations about their digitization progress.
For example, you may use it to find the most digitized series, or the ones with the most continuous sequence of digitized issues. You can also look at the timelines if you want to read content from a specific period.

An MDCU subscription is not required but this software has little use without it (unless you are considering to subscribe to MDCU).

It works on XP, Vista and Seven. XP and Vista users need to download the dotnet framework 4.0 (full version) from Microsoft:

Linux and Mac users may be able to run it with Mono, no promise though.
