Its a minor nuisance that when saving a new file, it always defaults to "Untitled-[X].txt" with Save as type set to "Plain Text". Therefore if you specify an extension and dont change the dropdown to all files (or correct type) it will save it like SampleFile.js.txt.

Propose that untitled files default to just "Untitled-[X]" with no extension and save as type set to all files.

Appears to be as simple as removing the mime type suggesestion in /src/vs/workbench/browser/parts/editor/untitledEditorInput.ts

    public suggestFileName(): string {
        if (!this.hasAssociatedFilePath) {
            let mime = this.getMime();
            if (mime) {
                return suggestFilename(mime, this.getName());
            }
        }

        return this.getName();
    }

Currently electron autoappends * . * on "all files", although looks like it was fixed v0.34.2+
Workaround in the meantime is to show no default text
