@nicolasfella Thanks a lot for your investigation! Then it must be an easy fix of simply adding a null check.

I just published a new `1.6.1` update which will hopefully resolve this issue. Please feel free to reopen if the issue persists.

This option already exists in the script's settings since version 1.4 or so. It's called "Delay before showing the assist"

You can try this CSS to show arrow only on hover: ``` /* Show expand arrow only on hover */ .Tab[data-parent="true"][data-folded="true"]:not(:hover) .fav .exp { opacity: 0; } /* Shift child...

@Elaws As an alternative, you can also try something like this – just shift the arrow and child count to the corner. But it may require some playing with numbers...

@Elaws It's important to note that I'm using version 5, and the snippet was written for that version. If you're on v4, it may be needed to inspect the tree...

Why including this functionality in Sidebery, when we have other wonderful dedicated addons to do that? For example, [Duplicate Tabs Closer](https://addons.mozilla.org/firefox/addon/duplicate-tabs-closer/).

It was already mentioned in https://github.com/mbnuqw/sidebery/issues/281, but since this ticket is quite old and generalized, I find it appropriate to bring it on top in a separate ticket.
