Add autocomplete for "tag searches" input in "Advanced Search" sidebar

[SwiftRedline]

Describe the feature you'd like

Hello!

I would like to have a autocomplete function.

We have a Tag called "NOC" and no one from my clients knows which tags are available. So a autocomplete or a list with all tags would be great!

Regards, Marvin
