Hi,
There are several tabs that appear when they are relevant: "Related Changes", "Conflicts With", "Cherry-Picks" etc.
Having dynamic tabs is useful to to avoid cluttering the web UI, but it is also confusing, since you can't tell the relation type without looking at the header.
The most common confusion we run into is between Related Changes and Conflicts With, since they're both quite common.
Is it possible to highlight the tabs (either the title or the entire body) in different colors? Do you have other suggestions?
