Move extensions buttons to sidebar
How to do this on v1.1?
You can't. It may be planned.
But you can post a request.
If you think a feature is useful and missing in Vivaldi, please make a request.
How to make a feature request for Vivaldi
If you think your problem can be solved by a missing feature, please add a request at https://forum.vivaldi.net/category/48/features-requests in the corresponding thread for your browser version.
Add one line in bold as a short title for the feature and 2-3 lines to describe the wanted feature.
Take a look at this. I don't know if he has managed yet, but it's your best bet atm.
@luetage thx. So I move .extensions-wrapper to sidebar.
But now extension popups opens inside #switch.
I understand I cant solve this problem without help of browser/extensions-makers?!
The mod just isn't finished. It's hard to accomplish. I wonder if OP ever managed and just didn't get back to us. You can't expect extension makers to support something that doesn't exist, especially because they are making the extensions for chrome in the first place. And I wouldn't hold my breath for Vivaldi to introduce this, but who knows....
Post in the other thread and show your interest.
