Sorry to bump an old thread, but I didn't see anything else like this when I searched for tabs and checkboxes.
I just noticed this today on Mac. When you have a checkbox as the first item on a line and you press the tab key, rather than indenting the checkbox, it inserts 4 spaces. In order to get the checkbox indented, you have to use Increase Indent Level. If this is intended behavior, would it be possible to someday get a setting to indent the checkbox when it's the first thing on the line? I tend to treat checkboxes like bullet lists where the bullet happens to be a checkbox, so it would be awesome to have bullet list indent behavior with checkboxes. I understand that I can just make a bullet list and then put a checkbox on it, but it gets pretty visually cluttered when there is both a bullet and a checkbox.
And also a setting to use tabs rather than spaces would be amazing :P
