Count of tabs is present in the extension icon. There is also present number of open windows, in tooltip, on mouse hover. I am against any useles options.

Actually better solution is to not to show Tabs Outliner window at all in the tree.... But there is more important tasks meantime.

> why not?

Did you read my comment?

Reasons why not exist. Yet maybe I will implement this as option.

You can open clone view, and never close it - it does not scroll.

Please vote on this idea if it is really needed by many -- it will be implemented. 

Yet before voting first consider that there is note functionality to add small, one line, comments to tab. And they have much better visibility than inline labels or custom titles. 

Also this will make pencil icon (in hovering menu) visible on every line, now it is present mostly only on windows nodes, and this make things a little less cluttered, and more easy to aim on window node for edit (so this is not something totally positive, and have own drawbacks and compromises, and this is why this feaure is absent by the way).

Also, for quick inline marks, there is plan to add possibility assign several custom icons to nodes (that will make this feature even more useless). 

Please vote on this idea if it is really needed by many -- it will be implemented faster.
