Tabs disappear after I delete a slide?

Totally agree Rachelle. It is frustrating. 

LeslieMcKerchie​  Looking back over this old thread, I am seeing your screen recording from 4 years ago for the first time. Your recording doesn't quite capture the flow that causes the frustration. Or, at least, it doesn't reflect my particular experience. 

If I have a module that has 5 sections, I like to open one slide from each section so that I now have 5 tabs across the top. That way I can move quickly from section to section by clicking the relevant tab. Then within a section, I use the vertical slide panel at the left to move from slide to slide. 

Here's the problem...  If I delete any slide in a section, one of the tabs at the top closes. So if I have my tidy little horizontal bar with tabs for my 5 sections for quick movement between sections, one of the tabs gets involuntarily closed and now I have only 4 tabs open and my quick navigation between sections scheme is no longer quick. I have to rebuild that 5 tab structure again so that I can bounce around between sections. 

The recording below demonstrates what I'm talking about. I THINK this is what many (most) users have been complaining about. 

I notice that near the end I meant to change one of the tabs to Section 3 but accidentally left it open to section 4. That was operator error, not a Storyline issue.
