I haven't seen this popup, but it suggests either to install an older version of ZArchiver or that you can't do it without ADB (which I will hopefully add soon).
It's there by default. It should be available next to MacroDroid tiles when you add tiles.
There is nothing way to store which trigger fired with one single action, however you can use if/else blocks to achieve that (if trigger fired 1,else if trigger fired 2...).
It is indeed a part of this variety of tasks, however it is already implemented. You just have to use UI Interaction. It's not often that a feature that basically uses other actions is added.
I don't see why that would cause that.
Pointer location is a system feature and not a MacroDroid feature though. You can disable it in developer options.
There are a few threads on the subject, you can search for them with the search function.

I can't be sure. Before, the wiki needed to be completed by volunteers only so it would be very slow but now that @Josué García is employed by @MacroDroidDev he should take care of it over time from what he told me. (Of course you can still volunteer if you wish too.)
I've had this problem since I've joined the forum where notifications and some pages occasionally just don't load, but it only happens on my phone on my network.
