How to implement tickler files? Use Threshold/defered tasks? Idea for a feature request

[Sinthoras7]

I have an idea for a feature request but I first want to hear your opinion and if you think, that there are better ways. How are you handling this?

My "problem":
I use sleek and todo.txt as my GTD next actions list and I think it is very suitable and convenient to also use it as the tickler list for tasks, which have to be done in the future. For that I can set a threshold date, but the problem is, that when the date comes, the up to then defered tasks quietly hide in my long list of tasks.

My idea to solve it:
Add a view into sleek, where one can see all tasks with a threshhold date, ordered by threshhold date. It should be visually clear, whether the threshold date is in the past or future. There should be a keyboard shortcut to open this view and ideally one could open it with just one mouse click from the standard view.

What are your thoughts on this?
