I was tossing some ideas around with Moin about topic timers earlier. There are often lots of different feature requests wanting more flexibility around these for a variety of things and I was wondering if having a dedicated Topic Timer config page would be more desirable. This would remove some options from the category settings and make those pages less full, as well as allowing you to have an overview of all of your pre-set timers/limits site-wide as a bonus.
I was thinking of it being a page where you could build your timers a bit like the existing UI for adding a topic specific one and they get added to a list (similar to Automation, or adding an alarm on your phone). With the right pieces in place you could then set a variety of timers for a pattern like [timer type] + [topics to target] + [condition]
This should allow for more flexibility in setting up specific versions for one or more categories, without being too complicated (for the admin).
