First off, loving WebIssues ! Well done on an amazing system.
Secondly, it would be great if I was able to group different attributes under a heading in the same Issue Type.
Something like:
Bugs (Type)
Week 1 (heading)
Attribute 1
Attribute 2
Attribute 3
Week 2 (heading)
Attribute 1
Attribute 2
Attribute 3
I'm not currently planning such feature. You can simply add prefixes to attribute names to achieve a similar effect, e.g. "Week 1 - Attribute 1".
