H5, H6: reintroduce level-5 and level-6 headings

[EduNetEurope]

Because since a recent version, h4 (and h5 and h6) are not shown in the outline anymore ! So there is easy way to know the link

(But I feel it's not a bad thing not to have all the headings showing up in the heading)

When I copy & paste text from Word, I can get level-4 headings.
How can I create a level 4 heading within Outline?

Solved:

• You can create new level-4 headings by typing ####, followed by the text.
• You can turn an existing level-3 heading into a level-4 heading by clicking CTRL+Shift + 4.

However, level-5 and level-6 headings do not seem to be available anymore.

We won't be changing this limitation, H4 already looks the same as a bold tag – it's not possible to distinguish headings below this size.
