Bookmark groups

I use quite big part of my tree as bookmark storage. While I could use to how it works, I have difficulties. So if it's a legal or recommended use to store my bookmarks here, here are a few ideas:

• It would be nice to be able to "lock" a group meaning all elements under it cannot be deleted with an accidental tab close, only from the TO window. So basically under locked tree parts, the tab close is equal to "save and close" instead of "delete".
• If I drag a link from a webpage to the tree, it makes a nice entry with the web page title (or the link title which is the same in Youtube for example). However I cannot easily bookmark the actual page I'm on. Of course I can the drag the current page link from the location bar to the TO tree, but it only shows the link there without the title. I have to open it at least once to get the real title. It would be much faster if in this case TO could use actual page's title.
• I'm not hundred percent sure in this, but when I choose a link from my bookmarks, now I always have to press shift so it will open in a new window. But if I have a locked (see first point) region which is used as bookmark storage, I never want to open the link in it's original context, but as a new window (shift) or as a new tab in the actual window (ctrl). Or another good solution could be that my bookmark opens in its original context, but if I open a link from this webpage (that I opened from a bookmark) it should open a new window. In oher words: if I open a link in new tab in my browser on a page which is in a locked part of the tree, the new tab should open in a new window else it will contaminate the locked parts..

Ok I think I can make illustrations for this if it's not clear.
