Description

add argument of changing readonly and modified icon.

Type of change

• New feature (non-breaking change which adds functionality)

Reference

[gegoune]

It would be good to add some documentation. Otherwise discoverability of this feature won't be too good.

Is the document added to the readme?
The following functions are also not described.

Isn't it unnatural that there is only one explanation for the function?

[glepnir]

vista_nearest already in readme.

[glepnir]

about this change. I think it's better to add description in readme.

[ya2s]

vista_nearest already in readme.

There is a description, but there is no details about vista_icon.
So get_current_file_name is already listed in the readme.

if add, I think should give details about all the functions you provide.

How is modified_icon used? E.g.: How do I provide this parameter?

I agree on the comments here that this should be mentioned in the README, even looking at the source I can't quite figure out how to provide this parameter.
