How to remove duplicates when combining pickers?

[qu8n]

When combining pickers, duplicate files are included in the result. Is there a way to restrict it to only unique files?

For example, if :FzfLua oldfiles returns

fileB.txt

And :FzfLua files returns

fileA.txt
fileB.txt

Then :FzfLua combine pickers=oldfiles,files would return:

fileB.txt
fileA.txt
fileB.txt

What I'm expecting:

fileB.txt
fileA.txt

The combine is currently very simple, it’s just combining the outputs of both at the shell level, I’ll have to think about it, maybe we add an option to pipe the output and use the shell to filter or a I’ll think about a different way to combine the contents at the lua level.

There’s a lot of features we can add to it (headers before new content, etc), maybe even switching previewer so we’re not limited to one type of entries, I’ll slowly improve on this very rudimentary version.
