I completely rewrote the SwiftUI code to consolidate and better manage all of the gradient settings data (grid setup, background color, point colors, and point locations), rewrote all of the code rendering the mesh gradient to use the new data format, and then added brand new code to export and import that data on macOS, iOS, and iPadOS. Yes, you can now export a work in progress and import the settings data later to continue where you left off. When you have created a compelling gradient design you can now export the settings data and later can import it back in to generate different color variations or make further refinements. The upgrade also adds the Gradiance icon to the welcome screen and adapts it to handle both light and dark modes, updates the help tips in the welcome screen to include the new features,  makes some improvements in the point selection popup menu in the controls, provides some minor enhancements to liquid glass usage, refines the regular, dark, clear, and tinted icons, and provides better support for macOS, iOS, and iPadOS 27.

This version features better support for macOS, iOS, and iPadOS 26 (adopting liquid glass throughout the user interface - including frosted liquid glass backgrounds for the welcome and controls as they float over the gradient, added icons for menu items (in macOS), and regular, dark, clear, and tinted icons). Improvements in the controls layout structure for better sizing on all platforms, refinements to control placement in Point Settings section and changing the Options section to focus on the Controls Position (with a new tab icon as well).

This version refines the point settings section of the controls by using a popup menu to select control points instead of a list. This change greatly reduces the amount of space required while providing the same functionality and can even be faster if you need to select points at different ends of the grid as you can do so with far less scrolling. I also squeezed a bit more space out of the interface by moving the color picker for the points up beside the new menu. While this difference might not seem like much on a Mac or iPad with larger screen sizes, it is a pretty dramatic reduction on an iPhone where space is at a premium. The control points are also now grouped with dividers in the new popup menu based on the grid setup to provide better context for their initial layout (for example, it is now easy to see 3 groups of 4, or 4 groups of 3, etc. and keep track of where the edges are).
