It came out more as a complaint than questions. Anyway can internal pages have status "complete" on browser start?
Can internal pages have tab.favIconUrl undefined instead of url to unaccessible theme resource?
And lastly I hope soon the media icon API will be available.
I completely forgot about this thread. This is not needed anymore because since opera version 32, when I call chrome.windows.getCurrent from a sidebar, it finally gives me current windowId instead of Id from active window. I always wondered why it always gave me the wrong Id, that's why i asked for this feature from sidebar's API, but it must have been a bug.
So it's solved and thread can be closed 🙂
We can't interfere with Sidebar size, at least not yet... I hope they implement 2 options; width state for each extension and auto-hide. Anyway it's a really good start 🙂
Until Opera improves bookmarks I'm switching to another browser. Slimjet, that name sounds stupid but hey, they have bookmarks sidebar and standard chromium bookmarks manager. I will check from time to time if Opera changes, but that's it for now 😞
