Known Plugin or Mail Issues
Unable to change follow-up subject prefix
As of El Captitan (10.11) at least, there might be a problem with access to the the preferences file (net.welchwold.mailfollowup.plist) which is preventing the customization of the prefix string. I am unable to investigate at this time.
Toolbar buttons disappear after upgrade
If this happens simply Control-click on the toolbar and chose "Customize Toolbar..." to re-add the buttons.
Toolbar button not functioning properly in compose window
When using the message composition window the Follow Up/Follow Up All toolbar button might not function properly and/or might not appear at all. I will look at this when I have time....
Installation Difficulty in OS X 10.7/Lion and later versions
OS X 10.8/Mountain Lion introduced new security measures that have made my old AppleScript plugin installer more difficult to use. Unfortunately I simply do not have the time to investigate the "right" way to distribute the plugin.
However two helpful users have sent instructions on how to get around the installation difficulties.
- Tim Lawson provides nice instructions on how to change the System Preferences (temporarily) to allow installation.
- Andrew Jung also provides nice instructions and includes some images showing what you might be seeing.
If all else fails, please try using the manual installation instructions.
MailFollowUp 1.1 Likely Incompatibility with Debuttonizer
The Debuttonizer utility is likely to conflict with MailFollowup 1.1 in some way. (I have not tested it.) At the very least, it is unlikely to be able to "debuttonize" the MailFollowup toolbar buttons. The reason is because Debuttonizer works by moving the toolbar button images in the Mail.app package, but the MailFollowup toolbar button image resides in the plugin bundle, not the application.
