Starting with Trac 0.11, it is now possible to customize the main and meta navigation entries in some basic ways.
[metanav] configuration sections can now be used to customize the text and link used for the navigation items, or even to disable them.
[mainnav] corresponds to the main navigation bar, the one containing entries such as Wiki, Timeline, Roadmap, Browse Source and so on. This navigation bar is meant to access the default page of the main modules enabled in Trac and accessible for the current user.
[metanav] corresponds to the meta navigation bar, by default positioned above the main navigation bar and below the Search box. It contains the Log in, Logout, Help/Guide etc. entries. This navigation bar is meant to access some global information about the Trac project and the current user.
Note that it is still not possible to customize the contextual navigation bar, i.e. the one usually placed below the main navigation bar.
In the following example, we rename the link to the Wiki start "Home", and hide the "Help/Guide" link.
We also make the "View Tickets" entry link to a specific report.
Relevant excerpt from the TracIni:
[mainnav] wiki.label = Home tickets.href = /report/24 [metanav] help = disabled
