Possible enhancement to category filters

[rogercreagh]

Currently if you filter the view by categories and select more than one category they are joined by an OR function.

eg: if you select both CatC and CatF in the filter you will get all items with either CatC or CatF or both assigned as categories.

There is a special option for "without categories" which acts like a virtual category of its own when used in combination. eg selecting Without and CatC and CatF will get you everything without any category as well as everything with CatC or CatF or both.

There is also an option on the three dots menu for Category filter to invert the selection so you would get all that have any other category assigned even if they also have CatC or CatF assigned.

I would like to see an additional option on the three dots menu for selecting the logic - with three choices Any | All | None

Any would be the same as the current situation (and would be the default) - CatC OR CatF

All would mean that you would only get items with all of the selected items assigned as categories. CatC AND CatF in the example

None would mean that you would only get items that did not have any of the selected categories assigned. ie a list excluding all items belonging to CatC or CatF or both.

Obviously if you've only selected one category to filter on then Any and All give the same result. None however would show everything that didn't have the selected category.

When you've got a lot of items and a lot of categories this would be a great enhancement, and also be a help in maintaining and updating categories. For example narrowing down the list to all entries about both cycling and holidays to get your cycling holidays in one list.

What do others think? Does anyone else see a use for this, or am I just odd?
