I recommend this change because sometimes a “-” for a bullet is confused with a minus sign, a dash (as punctuation) or many other text editing uses of “-” whereas a dot is not normally used in text (at least not frequently in English writing).
I realized that all unordered lists in this forum are marked in dots (writing in Markdown).
Yes, a hyphen is not a great piece of punctuation when it’s abused so much. A dash (– or —) would be better, but as you say a dot (•) is excellent.
I am pretty sure what we use is an en-dash. The markdown shortcut is a hyphen, but that changes to an en-dash.
Adding multiple options such as a “bullet” vs. “-“ would be very helpful. What would be great (perhaps a separate topic here) is updateing the “outline” took to be smarter… it it did a hierarchical outline since as Roman numerals, capitals letters, numbers, lowercase letters etc. on demand by using the tab key, this would be exponentially helpful. At this point I have to force the formatting line by line… which takes time and makes the application less useful.
