Mextures App for macOS
Although this is not something we are currently developing, it is something we are working on in our product line.
We've released Mextures Premium Textures for Photoshop which are high-resolution textures with custom actions that apply and resize and blend the textures on your image. You can check them out here: https://www.mextures.com/store/
To see a demo of the textures/actions check out this video: https://vimeo.com/148732141
We are also releasing a brand new plugin for photoshop that will allow you to use Mextures in a similar way as the app, as well as introducing our new product line: Color Grade Presets.
