Filter more than one category

[gerhardm5]

I am able to addict more than one categories to any contact. So it should be possible to filter after more than one categories the same time, f.e. "collegues" and category "concurrent", only collegues show all of them, the additional "concurrent" only that part.

That seems useful. I put it on my todo list. But it will take a while ...

I am currently working on hierarchical (nested) categories:

Is that what you mean?

Although I'm not the OP, I think this would only solve part of the general problem (admittedly congruent with the given example).

Nested Categories would only solve the case where a second category was used to contain a strict subset of the contacts in the first (i.e. colleagues that are current, excluding former ones).

But I do also have categories that have overlap that aren't a strict subset of each other (e.g. friends I regularly play soccer with that are also part of my boardgaming group). It would generally be helpful to be able to filter my contacts by selecting two or more categories at once to get the intersection of contacts therein, without having to curate another category manually.

Hm, I will have to think about that.

The nested category stuff is now part of CatMan 3.3 (for Thunderbird 68 Beta).
