After having qualified the type of work (Analysis, Development, ...) by using the Worklog Types (introduced in response to JRA-1780) ,you want also specify if the related spent time is chargeable, or append additional details related the logged work.
How it has been solved ...
Minyaa introduces the notion of Worklog Fields.
Since the solution may differ depending on your final needs, it has been decided to allow you (or your Atlassian Partner) to define by yourself these Worklog Fields.
Minyaa(for the moment) provides only a sample Worklog Field, but it should be enlarge to new fields in futures releases.
How it Works ?
Minyaa Time introduces new module-type allowing Plugin's developers to build their plugin with they own Worklog Field.
By default Minyaa Time defines a first Worklog Field : Chargeable. which provides a simple checkbox to specify, by example, if this related spent time is chargeable to your customer.
