Google + (plus) 1 toolbox service is wrong size

This isn't anything the module has control over.

Actually, it appears that there are Google-provided parameters that you can apply to the +1 service by using the "Customize services" tag, including size. Here's an addthis.com forum post about it.

And here's the Google API page describing the parameters.

Here's how to do it with from the AddThis module interface:

1) On the AddThis admin page, click the "Customize services" tab.
2) Open the "Add a service customization" fieldset.
3) For service code, use google_plusone
4) For class, enter addthis_button_google_plusone
5) For attributes, enter g:plusone:size="medium"
6) Leave title blank and save it.

Thanks, works like a charm!

Guys, could you tell me how to achieve the same thing in 7.x-4.0-alpha1 version of this module?

There's no "Custom services" tab or, at least, I didn't find any. Instead, there's a field "AddThis custom configuration code" with exampe: var addthis_config = {}

Does anyone know what to do next?
