Add configuration option to stop report refresh

[joshdoyle]

Description
I want to work a limited list of tasks (10 for example) and see the list decrease as I complete them. I can limit the number of tasks with a custom report. However, once a task is completed, the report is refreshed with a new task so that I always have 10 tasks.

Solution
I'd like a config option to prevent the report refreshing until all the displayed tasks have been handled (completed, deleted, deferred, etc.)

Hmm interesting. I think I see why that would be useful but it might be out of the scope of the tui (unless an implementation is easy).

I’ll look into this after fixing v3 issues + a rewrite. Thanks for opening the issue!
