Tags 2.0.2 fixes some annoying crashes and bugs. This free update is recommended for everyone.

• Fixed an issue where clearing the global keyboard shortcuts did not work
• Fixed an issue where deleting a tag could lead to a crash of Tags
• Tags crashed for certain folders in Finder (e.g. Applications)
• Improved support to work together with MailTags
• If you have configured Tags to hide its Dock icon, than this setting is respected when you update the app. Unfortunately this will start to work with the very next update.
• Note: Firefox 3.6 is currently not supported as it does no longer provide an Applescript Interface
