Do you have the "Don't group pinned items" option checked?

You might want to create a new suggestion ticket about it.

I need more details to try and reproduce it.

Please provide me with:

* Your Windows version - 7/8/8.1 32/64 bit.

* A screenshot of the tweaker's options you're using.

* A screenshot of the taskbar's properties.


As for the hover delay, see:

In v4.3.1 there's a registry option to hide the start button in Windows 8.1.

You might want to try it out.

Have you seen the options Taskbar Inspector provides?

Having said that, it sounds like you're using the "Combine when taskbar is full" taskbar configuration. The tweaker doesn't support controlling which buttons to combine when this configuration is chosen. There's an open ticket for that, you might want to vote for it to express your interest:

Here's an old version of the tweaker's page:

You might want to read the third question in the FAQ, especially the BTW part.
I've removed it eventually as I thought it's quite obvious. Perhaps that's not true for everyone...
