New idea: we have large number of Activities in our instance of Redmine, but most of time we use only cca 5-6 activities from total of over 20.
When can be nice to have ability to highlight only preferred activities... In admin part, there can be simple checkbox [x] Favorite activity, checked by default, or there can be something like [x] Minor activity, in the list of Enumeration / Activities.

When adding new ticket, there can be separator between favorite and minor activities or, there can be listed only favorite activities and all activities can be expanded by some gui element (small button or "Show all activities" in select box).

This feature should be optional, because smaller teams will probably don't like this feature...

What others think?
