Not possible at the moment, but it might change in the future. The plan is to allow constructing custom trees from Lua including adding nodes that don't correspond to any...

I'll comment here when I add relevant API.

Might be difference of measurements. Since v0.12 Vifm calls `fdatasync()` every 256 MiB to avoid hanging the system (see #518) and shows realistic speed of data transfer instead of speed...

Looks like `cp` uses `copy_file_range()` or `read()`/`write()` on file descriptors, tries to advice kernel on how file will be used and picks buffer size in a complicated way. Vifm just...

I've added "datasync" to 'iooptions'. @savchenko Maybe you could try measuring the speed after `:set iooptions-=datasync`, it might be faster.
