Plug Tools is a small, free application that helps you to keep your plug-ins up to date. It scans your plug-ins folder and shows you all the plugs with version numbers in an easily modifiable list on the left side. On the right side it loads Digidesign’s plug-in compatibility grid which you can use as a reference to cross-check the current version and mark your plug-ins accordingly. No rocket science, just a super practical helper when upgrading.
