Right now we only work with Adobe Photoshop, Illustrator, InDesign, Figma and Canva.   We'd love to be able to use other tools (Adobe XD, Sketch, Invision, etc), but there are so many apps out there for Web/Graphic design and it'd be impossible to accommodate everything.   In order to support other apps, our whole team would need to be trained on all of them so if your designer is away, another designer would be able to pick it up.
