Bookmarks

Hello Zoho People! I have a request which I would Love to see in an online wordprocessor:
Bookmarks. Bookmarks rock. Many people don't know much about them, but I have become dependent on them since using Open Office (which the school that I am at no longer supports because they are facists....) They have a brilliant Bookmark system which allows one to quickly and easily move through large documents.
I have been using Buzzword for a while, but it has begun to annoy me, it no longer has good customer support since it became part of the huge conglomerate which is Adobe. Therefore, I wish to try Zoho again because it seems to be the best online wordprocessor in existence and is only getting better!
Other comments which I suggested to them which Zoho may benifit from are:

2 - A floating message thing. Something that you could write comments in but wasn't attached to a specific line. I have created separate documents for this purpose, but it would be nice to be able to have it to the side. Like Macintosh Stickies or something. You do have "Notebook" so this is less of an issue than it is in Buzzword....

3 - It would also be nice to be able to re-name a document for your organizer alone. Not that it would affect the true name and how others saw it.

4 - A vertical ruler.

5 - Another thing that would be great is a 'mark as unread' feature, like e-mail has, in case I opened a document and didn't find what was different or just wanted to mark it so I remember to look at it when I get on next. And on that note, it would be nice if Buzzword could temporarily mark (with an underline or something, perhaps a colored bar to the left) changes that happened to the document.

6 - A feature which would show what additions another contributer has made.

I apologize if you have already addressed some of these issues. If you already have, YOU ROCK! and you are SO much better than other online alternatives.
Thank you.
