A paid Tango Pro plan enables additional branding control for:
PDFs - basic customization of PDFs including removal of Tango watermarks on screenshots and the addition of a custom logo.
HTML and Markdown Export - removal of Tango watermarks on screenshots
Embed- removal of "Created with Tango" on title slide and Tango branding on the final slide
Additionally, Pro users are able to designate custom action box colors (the ones that show up on screenshots while capturing a Workflow) in their Workspace Settings tab.
At this time, there is no customization ability for Workflow URLs or the Guidance panel.
