Not sure if this is intended to be a feature, but it's causing issues for me.

By default, all programs that I use on a daily basis create files with 644 permissions (owner: read/write, group/others: read).

However, Peek creates files that can only be read/written by the owner, and nobody else can access them. This causes issues for me, when I want to share the files.
