I want to show the username in the title of the index.html. Is there some way to achieve this? And do we have a widget to show the username somewhere in the theming? I know there is the login button widget. But can we use this in our theming, so we can display this on all pages?
You can make an html element in the theming with a classId="ShowMyUserName" (this value is just an example, take what you want).
Make a simple form that only shows the username. (FormShowUserName).
Place the FormLoader widget (AppStore) on your homeform.
Set the form to FormShowUserName.
Set the Shared Node Id to 'ShowMyUserName' and the form will be placed in the theming where you want.
Apply a css to the FormShowUser to remove the spacing if you want.

You should be able to edit your HTML and add a little division in which you place the currentuser-object (like a small widget).
