Would like to create a simpler "Create Task" form for our Workboards.
The deeper issue (which is already discussed in T6064 for example) is that Workboards are currently too complex for the purpose of quickly adding tasks and changing their titles, partly because they default to the "full" edit/create forms from Maniphest. Below are some examples from Trello:
"Create task" link
Simple "Create" form
Simple "Edit" form
