Questions

Can you clarify the meaning of this phrase on line 109: "detects the used line ending." When I receive this feedback I'll restructure the sentence so that's more readable.

On line 83, when you say "uploaded to cloud" are you talking about a specific cloud or clouds in general?

Also on line 83, regarding the phrase "path on disk" you are talking about the hard drive on the user's PC, right? If my interpretation is incorrect then I will alter the text.

Note: Thanks for a fantastic app & guide! I recently started using MarkText, which I consider to be an awesome application!
