Bubble notification on tab

Is it possible to add a bubble like notication on the tabbar for each tabs?
I am testing the sidebar and I thought the bubble notification also applies to tabbar but it is not working on my side.

I would like to display number or count on specific tab if there is a new data.
How to do that?

Is the dhtmlx v6 tabbar have bubble effect?

Unfortunately there is no such possibility to add such bubble notification to a tabbar.

Is there a plan of adding one on next release?

we have no such near plans.
