Better gradients

Background gradients now support radial and conic types in addition to linear. A new visual editor lets you drag color stops along a gradient bar, adjust the angle, and position the center point with a 2D picker. You can add as many color stops as you want and preview the result live. The default colors are now  Cavai Pink and  Cavai Gold instead of the ones shown in the video.

Custom CSS works with rich text

Custom CSS now correctly overrides rich text formatting in both blocks and flow operators. This applies to all rich text styles: bold, italic, underline, strikethrough, color, and font size. The style hierarchy is custom CSS → rich text → block style, so custom CSS always wins. Text in flow operators also no longer overlaps the footer action icons.

Block group fixes

Groups now get consistent names whether created or duplicated, with correct numbering that includes nested groups. Blocks pasted or duplicated from inside a group keep their properties and placement.

Keyboard zoom in flow

Typing +/- in input fields inside the flow editor would zoom the canvas instead of inserting the character. This is now fixed.
