I though that It was as simple as 2 icons, one for each state, so they could be different depending whether On or Off.

List update - 2017. 11. 14.
In v49, one feature from the list have reached the stable channel. It is removed from the list. Its stats were the following:
Rearrange Extension icons on the toolbar
I don't want to answer: 11
Not important: 56
Somewhat important: 99
Very important: 77
Must have: 90
That's not a solution to my problem.
The createObjectURL() creates references to the files stored in the memory. It is useless to send these references to the background script, because when the panel unloads, the references cease to exist.
By future updates in don't mean the next one! We are working on some of these, and they will be released once its ready.
Then what is the line in the changelog?
OK, I know what "future updates" means, but that line drew my attention.
And you should update the API reference, because it is outdated. Still states that the badge is not supported.
It's a wonder this hasn't been implemented yet.
The "close" button is by the "open tabs", "minimize", "windowed" and "synchronization" buttons, as well as any nearby extension icons.
There's nothing more frustrating than misclicking it and losing an entire window full of tabs, all because Opera's settings don't include an opt-in prompt for confirming whether or not someone really intends to nuke their current window.
