Best search engine extension for Google Chrome/Opera?

Question

Opera

What are some good search managers for Chrome. otherwise, as is known in the browser, for unknown reasons, the number of added searches is limited to only FIVE!
I am using
Search Center ,
All in one web search ,
Selection Search is updating!
Another interesting update! search engine.
SelectionSK
It is unusual in that search forms are added in the form of bookmarks in folders.
the bookmark must contain the search address.
A folder is created in Imported bookmarks, and new ones are manually added there. Folders can be nested, sorted, icons are displayed.
The extension can also highlight words in different colors.
here are a couple more search managers, albeit old ones) (you need to add searches manually)
Advanced search by selected text
Advanced context menu search
Simple = Select + Search
What I would like and how I see the ideal manager =
● Search from the context menu
● Export-import settings
● Multi-tab menu with searches (for order)
● Convenient quick search management (moving, auto sorting, editing)
● Quick addition of search, directly from the page
● Search and highlighting words on the page
● Search icons
● Search by image
● Synchronization, service, collections....
