Oops realised I haven’t done a post about migrating your settings.
You want to go to the Opera menu, then settings, then Import and Export and choose Export Bookmarks as HTML.
Then in Maxthon, (1) go to the Maxthon menu , (2) then bookmarks manager, (3) Menu, (4) import, (5) from HTML file.
You need to first locate your search.ini file, it should be in your opera profile folder. Similar to above.
Open in your editor of choice.
You are looking for the URL that contain %S.Then in Maxthon, go to manage search, add and then paste in the URL from the ini. This also works for Multi search.
I haven’t imported my Notes and Maxthon’s RSS reader is pretty poor.
