Idea: Be able to open scripts without filename extensions in text editor by searching for a shebang.
Currently, shell scripts without a filename extension aren't opened in the text editor. Since few people tend to give their scripts a .sh, .bash, etc. extension, you could instead search for a "#!" in the first two characters of a text file as a criterion for opening it in the text editor.
This would require a change in the main server repo as that is what determines the file type to enable the files_texteditor. I'm not sure how or if those people are monitoring these module projects.
Right now mimetypes are being managed via file extension. However, I wonder if there is the option to determine the mimetype like the linux program file does or would there be issues with performance or complexity? I'm not sure but it might be fun to look into why.
I would recommend reposting this in the server repo.
