[Feature]: Create a task by copying an existing one

Is your feature request related to a problem? Please describe

Sometimes I create several similar tasks.
E.g. I have 3 features to develop, and all of them need to be developed, then tested, then deployed. This sums up to 9 tasks, 6 of them being similar copies of the 3 initial ones.
There is no added value to create all of these 9 values when they are very similar.

Describe the solution you'd like

On the detailed view of a task (i.e. /tickets/showKanban#/tickets/showTicket/nn URLs), add a Copy button right under the Save buttons.
Pressing this new button would then:

• first ask to save changes if some of them were added to the task since its opening — or not ask if no changes were made
• then redirect to the /tickets/showKanban#/tickets/newTicket URL with all data from the previous ticket pre-filled in this window. The title field would be pre-filled too, and would be prefixed with the [COPY] string

Best regards
Valentin
