There have been various posts on how to present unread mail in the Inbox as Red (as with previous versions) rather than the new default black bold. The solution is to edit the notes.css file which is buried in a ‘branding’ jar file and other posts detail where this is held on the Windows platform. Until IBM provide a user interface or preference setting for this (or knowledge on how to produce new themes as widgets is more readily available) I thought I would share where the notes.css file is held on the gold 8.5 on Mac.
The jar file holding notes.css is held within the Notes.app package, you will need to use Finder to highlight Notes.app right click on it and select 'Show Package". You will then get a Finder window and you can navigate inside the notes.app package. Navigate down to Contents\MacOS\Shared\Eclipse\Plugins and within the Plugins Directory find com.ibm.notes.branding.8.5.0.20081211-1925.jar. Right click on this and open with an archive editing tool such as Springy. You will see a directory called themes and within that is notes.css. Copy notes.css to a temporary location and use a text editor to change the section headed mailtable>row>unread from color: black; to color: red; Then save the new file and drag it back into the archive, replacing the original.
You should do all of this whilst Notes is not loaded and probably take a copy of Notes.app before you start. Once you’ve completed the above reload Notes and you should have unread mail in glorious red!
