Thanks for telling me about the Bookmark Importer, lem729. I have just tried it, but it has a few probelms.
- Some bookmarks are shown in the bookmark tool bar, and the rest of them is all hidden. There are a few problems with this.
It is inconvenient to get to the hidden bookmarks because it takes extra time, and this extra time seems a little too much.
Another problem is when I show my computer screen to other people. My bookmarks are basically secret. I do not want to show them to other people, but they are in the bookmarks tool bar so everybody can see. I often show my computer screen to students in my class. You can imagine an awkward situation when I do it with Opera 20.
What I need is the same bookmarks system as the one in Opera 12. That way, you can hide your bookmarks easily by using folders.
I have found that the same thing can be done with Opera 20 too, by dragging and dropping bookmarks folders into one folder. But it takes a lot of time to open this folder, and it is too inconvenient. "Over 5000 bookmarks" is not a joke; it is true, and a folder with 5000 bookmarks and a lot of sub-folders seems to work too slowly. Also I do not like the way bookmark folders work: it is just like Firefox bookmark folders. Those Firefox bookmark folders are terrible when you have hundreds of bookmarks in one folder: it takes too much time to go through bookmarks from the top to the bottom.
I need to go through thousands of bookmarks quickly and efficiently every day. So far Opera 12 is the best for that.
- Bookmark folders open too slowly when thousands of bookmarks exist in them.
This is what I have just talked about.
The only problem with Opera 12 is speed, not functionality, I do not want Opera to change functionality. In any case, the reason I use Opera 12 is its functionality, not speed, and I am satisfied with the functionality of Opera 12.
In conclusion, the Opera 20 bookmark system is useless.
