Thanks a lot sir. Nice work!

Any chance to make this compatible with fzf_action (CTRL-T, CTRL-X, etc).

+1, useless without that. But thx, it is beautiful.

Is it just me or calling this function takes at least 10 seconds?

It only takes ~500ms for me... But I am running on a newer Macbook Pro with at least an i7 and 16Gb of ram...
