Description
The TracQuery page, which is linked to from the View Tickets* menu (bottom right), contains a section on saving custom queries, which says:
Trac allows you to save the query as a named query accessible from the reports module. To save a query ensure that you have Updated the view and then click the Save query button displayed beneath the results. You can also save references to queries in Wiki content, as described below.
I wasn't able to find the "Save query" button, which I assumed would add another section for custom queries to the pre-configured ones on the "Reports" page (see also this comment).
If this feature isn't availabe (to end users), this section should be removed or annotated. If it could be enabled, it would make a really helpful addition to the tracker.
*Tangentially related: this is the only menu whose heading doesn't match or so much as include the wording used in the menu tab/button ("View Tickets" vs. "Custom query"). For consistency and because of what the page ultimately does, it would ideally reference "Tickets" in its heading. (The search form itself doesn't need its own heading, IMHO; it could be replaced by regular text leading into it.)
