It would be great to be able to adjust the colours and logos that end users see when they receive documents to sign on Lumin Sign - in both the app UI and also in the emails. Some customers want it to appear more professional or in line with their overall brand colours but might not want to go to the effort of changing all of the colours so we could provide some preset 'themes' to choose from and then let them edit the themes and add in their logos as well.
