You may use sync using your Opera Forum User/Password and save also open tabs as well as your custom data.
This is what Opera Sync syncs:
But make a Folder Back Up it's a full bckp, so Sync.Opera.com do not bckp some stuff like extensions and it's config, other stuff don't remember since I use Sync but make Folder Bckps, also easy to manage multiple profiles.
To find the path:
OMenu > About Opera > Paths >> Profile
Here's a BIG problem with this add on , in case the dev is reading, when you restore a session it should not immediately load all the tab and break my system in half. I should only load one tab and then load the others when you click on them.
Oh, I don't need it to work perfectly. I know it won't work perfectly on every page, I'm fine with that. I'm just looking for what does the job best across all pages, provided it can:
be shut off with clicking on a button or a hotkey
that I can adjust font size
that I can change font color for links
