It would be nice if you could use a more descriptive topic titles. 
It’s kind of already possible, with “Application Templates”.

For a more user-friendly (without scripting) implementation, it would be nice to see some mockups / suggestions. There should be a menu that allows you to hide/show panels. How to deal with the fact that panels are dynamically displayed depending on the context or object type…
I’m not sure about the ability to hide each button separately, (for me) it seems overkill. But, for example, custom panels where you can put frequently used items is a good idea.
