Thank you for an excellent software!
Will the new gui framework implement widget styles like the old versions 3.19 and below?

The widget styles options are in Settings - Behavior.

Thanks for the answer, but I carefully read the news on the site and study the changelog.

It would be desirable to have settings like in old versions of the client (3.19 and below) such as:
Toolbars: OS Default, Icon Only, Text Only, Text + Icon, Text + Small Icon, Horizontal Text + Icon, Same Sized Buttons, Mixed Sized Buttons, Small Same Sized Buttons, Small Mixed Sized Buttons... maybe some other way

Hope to explain clearly. Thanks.

Tixati Settings -> User Interface -> "Widget Styles" button does not work.
