I was not satisfied with the default bug tracker queries.
Grouping by default is probably good if you want to focus on getting things done.
But what I really want to know is what changed recently.
I played around with the "Show All" url and made a bookmark that satisfied me:
Then I tried out "Your Queries" and made an equivalent query named "Show Activity".
Before creating it I tried setting the "Latest" query to "leave in", which
created a private "Latest" query. (not sure if this is intended)
The bug: I am unable to remove the original "Latest" query from my "Your
Queries" section, and I can't delete or remove the private "Latest" query.
