I really like the tags that we can use in our posts. However, I think that the quote blocks should act like code blocks in that they preserve the spaces/tabs, etc. In this way we could copy text from a help file - copy it to the clipboard - paste it into notepad - and then copy that into the clipboard and paste it into a quote block on the board.
The way you must do it now is place the quote inside of a code block which is not a major problem, so its just a suggestion. After all when you are quoting something or someone it should be verbatim - including spaces and tabs.
