This would make UTL the ultimate productivity tool - I need it to be able to recreate some of my saved searches from Toodledo, and then I can also switch to using UTL on desktop as well.

It's a basic requirement that will come up for anyone who uses it intensively, one time or another.

i use utlimate todo list payed version for a couple of years already and i find it no 1 tool in my android device. up to my knowledge it is easy to implement negative condition in filters and it would be very helpful and make it even more profesional tool. please implement it in the next revision.
regards, AM

need this badly! I need to create a custom view that only shows tasks with no tag, but can't! It's creating redundancies that are killing me!

Under review since 2015. Did you get a result?
Would be really helpful to exclude some tasks in an boolean search.

+1 for the request for "not equal to" tag

would be especially helpful so as to avoid redundancies in widget lists, for example one widget listing tasks due that are not repeating, and another listing the tasks due that are repeating

here is a feature that I use in toodledo that is not in ultimate todo list. I was wondering if you would add it.

Toodledo has the ability to exclude items with a specific tag when filtering.

As a result, when I open ultimate todo list I see dozens of tasks that are not in the same view on toodledo.

Any chance to be implemented?

I need this feature also. The idea is over two years old. When do you plan it?

Please include Start date and due date here

I am really looking forward to this feature.Title and Tag... toodledo can do.

Will the planned feature allow negative filtering on multiple fields or multiple elements? For example: tag is not financial and tag is not kids. Essentially, will this add an option for any filter to be negated in any combination, including combining negative and positive filters (i.e. is context x and is not status y)?

Actually I would summarize all the previous comments: for all the filterable fields it would be great to have this "isn't" feature.

I would like to filter on Title as well. "Title contains/title does not contain.." etc.

toodledo allows you to select "null" tags, want same capability in UTL

Would be nice to include status and priority as well even it is not so critical comparing to context, goal or tag
