you can report issues in the github repo. However, if you want to ignore files and folders you need to pass those patterns to the function. For example, you want to exclude .git and .png then you need to run the command:

    notes -x *.git/ -x *.png

in general if you want to exclude hidden files and folders you need to run it with -h true which excludes hidden dirs and files, so you can run

    notes -h true -x *.png
