3 to be improved

[gmx]

I have update it to Build 0022, but I have not uninstall other alternatives. I am waiting for some features I need very mcuh to be available.

1. I find Add Bookmark in right-click menu becomes dark (before it was grey), but it still not works.
2. Document properties such as title and author can not be changed even if I can put the cursor into the fields.

I am not sure if it is due to something wrong in my PC or just this build can do that. If these two functions supplied, I think it is almost perfect.

3. I like to read with the paper color changed, usually darker than the pure white. Anyway, this is not so of priority
