Option to hide launcher items

[felipehw]

Hi, thanks for this awesome extension (now updated for Gnome 40).

My main use case is to find an opened window among a lot of others.
For example, to find a specific PDF among 7 windows with different PDFs (using Okular) across some workspaces.

But I don't use to launch new software. So, the current behavior ... showing a lot of lines of launchers ... is convoluted.

I would like an option at preferences to hide launcher items.
