Should tasks be categorized by categories or tags - or both?

With Flyspray 1.0 tags are supported. They are just labels that can be applied to tasks.

The differences between categories and tags in Flyspray 1.0 are:

##Categories

####Good

  • A category can have one default assigned user, who can gets assigned automatically to each task created in that category.
  • The category filter is available in the extended search

####Neutral

  • Can be grouped in a hierachy tree.

####Bad

  • A task can only be in one category.

##Tags

####Good

  • multiple tags per task

####Bad

  • not searchable or filterable yet (planned for FS1.1)
  • no grouping of tags (taxonomy)

##TODO
