Hello JoomDonation Team, first I want to say thank you for the wonderful work and support.
It would be an enrichment for the work with OS Services Booking if we could adjust the color in the layout settings. Maybe a field for color codes under your existing color fields? That would be a great benefit for the individual adjustment to the corporate identity.
Without deeper knowledge of CSS and the programming of OS Services Booking t´s very hard to make those adjustments on our own. Especially without asking you so many times for help :S
