Add Not/Negative-Filter

[Dubidubiduu]

Is your feature request related to a problem? Please describe.
I just want to know which is high priority and not done yet. Or I want to filter by "in edit" which aren't mine and also not from user x.

Describe the solution you'd like
Giving a Not filter for ppl and tags.

Describe alternatives you've considered
Workarounds as user:
A) Moving due-date and use existing due-filter. But then I lose information of the original due-date.
B) Instantly archive cards that are done. But I just want to see what we have archived for a time before archiving these...

Additional context
Guess it should be a second checkbox right next to the positive filter.

Any suggestions how this can be done from the user interface point of view? If we add such advanced filtering options we need to make sure this is obvious and doesn't add to much clutter to the filter view.

I thought of something like this, just imagine these activities are users or labels. Description of those rows would be True/False or Positive/Negative. Guess it would be neccessary to shrunk some white space.

Tris proposal could be related to nextcloud/server#4851

That one is the same proposal for tags.
You could:

• pick some proposed solutions from that other issue
• try to see if an unified approach is possible

Thanks in advance!

I'm not sure about adding such advanced options UI wise as this will make the interface a lot more complicated. As an alternative we could think about adding and or operators to possible search queries #286
