Always Show Address Field

The address field keeps its background and its bookmark, split view and site buttons, as if you were pointing at it. You can see where the field is and reach the buttons without hovering first.

Tabs in the sidebar	Tabs at the top

Turn it on

Open Dia → Settings → Patches and switch on Always Show Address Field. Or run:

diatweaks enable showAddressField

Works with

Hide Toolbar. The field only shows while the toolbar does.

FAQ

Does it show the full address?

That's Dia's own setting, and this tweak leaves it as it is.
