I have noticed some of the following things that irritates me about the word editing in the visual site designer software.

1) I can't do bullets.

2) I can't use tab's to try and space things out nicer and evenly.

3) I can't use the space bar to move text over if I wish to.

4) There is no justify for the text.
Ex: There is left, right, center but no justify.

5) When I place a picture bullet next to text, in the Visual Designer it looks one way, but when upload to a site it looks another way.

If you mean within the text box editing, I'm pretty sure that's deliberate since HTML browsers "eat" up extra spaces between letters, ie "a__test" (where a "_" denotes a space here) is rendered as "a_test".
