Please help with authoring tool questions

I am doing a project for school that involves creating help files for a html
authoring tool.
If you could help me with answers to some questions it would really help.

1. What tasks do you expect an html authoring tool to help you accomplish?

2. What do you expect from online help for a html authoring tool?

3. What audience do you think a freeware html authoring tool is directed
towards?

4. What format is most useful for online help?

Thanks to any of you who take the time to help.
