so when I am in my Downloads folder and use my Up and Down arrows to navigate the menu I experience full freeze when something like Linux distribution 1.9Gb iso image is selected.

one thing it does not even need to preview these types of files, the second: preview is implemented in a wrong way so it (supposedly) tries to read the file entirely when only the first "page" is enough.

also I don't quite understand why file picker works the way it does - I would expect it to list only current working dir files, but it lists every imaginable file on my desktop.

ah, it displays me my home dir, but why it does so if I've opened helix with hx rust/temp/iter-test

This is likely related to #338

Edit: Never mind, I misread.

Hmm, are you using 0.4.1? If so, can you try to build from master to see if it works?

If you start helix with a directory as the argument, it will use that directory. Otherwise, it will use the directory your shell is currently in.

I don't understand, I mentioned the directory, but helix remained in the current one (home)

Oh, I see. I imagine it should work like that, but apparently it doesn't. I guess I can try and fix that and open a PR.

We should skip rendering both binary files and files over a certain limit (10-20MB)
