What's the right way to customize the Plone toolbar through the web (TTW)?
I'd like to add an additional entry to the toolbar or will I need to go to the filesystem for this?
I don't believe there is a way currently. Even in the filesystem its not that easy. You don't get full flexibilty over the order for example.
You can add items to the actions menu I believe.
I would add a github issue about not being able to configure this in site setup.
A way to manage it through the registry and bring forward a control panel in site setup would be nice. Just working out a few implementation ideas
You can still use portal_actions to add a toolbar item.
Woo! I'm on a roll
Too late to throw it a summer of code student though.
