The suggestion:

Implement a new action in Ultimate To-Do List (either in the app itself, or in the form of a new action for its Tasker plugin) called "Snooze all active reminders", which (surprise!) will snooze all currently active task reminders (nagging or not) for X hours (where X is a user-supplied parameter).

The motivation:

This would be of HUGE help to me (and most likely also any other heavy user of task reminders) on a daily basis!

The reason for this is that during my work day I have a (quite often quite large) bunch of task reminders (some of them often also of the "nagging" kind) for tasks that I hope to complete during the day. Oftentimes though, a bunch of them are not completed at the end of the work day after all (due to lack of time from unforeseen circumstances etc), and at this point I do NOT want all these reminders (and their nagging sounds/vibrations) to clog up my phone when I'm off to fetch the kids at daycare, at home eating dinner with my family etc, which means that I currently, in a very tedious fashion, have to bring up every single such task and individually snooze it in order to get rid of its reminder until the next time I will be able to focus on it (normally later in the evening), which is a VERY stressful and repetitive procedure (especially when you're already late for the kids due to uncompleted tasks at work...), which I'd very much rather like to be able to do in a single click, which is why I suggest that you make this an easily accessible functionality inside the app, and/or a new Tasker plugin action!

PLEASE implement (and vote for!) this, since I'm completely certain that any busy person who uses task reminders has this problem and would love this solution for it!

(and finally, as a developer myself, I'm quite sure this would be a VERY simple/quick thing to implement for you, so good time/result payoff too)!
