Support more than one word file

[alem0lars]

As far as I understood, the support is for just a single spell file.

However in my real use-cases I need the system-wide dict, and also the dict file filled with custom words I've added (zg command).

So in this case I need at least 2 sources for look.

You can merge the files.

Is that done automatically?

Because it is very inconvenient to merge files manually EVERY time you press zg.
Also look command natively supports more than one file to lookup solving that issue effectively.

Hm.
But I don't have time to implement the feature.
You can add it!
