Version 0.5.1 - SuperCards

Improvements

One-Click Math & Code Blocks: The Math and Code buttons in the EditorToolbar are now “armed tools” — click once to arm, then click anywhere on the stage (or use the stage right-click menu) to drop a new block. A new ArmedTool type and armedTool slice in editorStore, with setArmedTool / toggleArmedTool actions, replace the old multi-step button flow
Stage Context Menu Block Creation: Right-clicking the stage now offers Math and Code block creation directly, matching the toolbar’s armed-tool flow
Precise Click-and-Drag Text Selection: Click-and-drag inside text elements is now noticeably more precise and stable, dramatically improving the feel of selecting and editing text on a card
Paste from Block Input Right-Click: Math and Code block input fields now expose a native right-click → Paste option, so you can paste TeX or code without reaching for the keyboard

Brain Dump Context Menu Focus Polish: Brain Dump context menus now use custom focus classes that kill the default blue WebKit outline on the auto-focused first item, and arrow-key keyboard navigation mirrors the hover state — keyboard users get the same clear feedback mouse users do
Library Empty State Consistency: The empty-state styling for deck containers in the Library grid view was updated for visual consistency with the rest of the grid
Deck-Deletion Guard: Added a guard that prevents deleting a deck while it’s currently open in the Card Editor, avoiding a class of inconsistent-state bugs

No More Phantom “Selected” Ring on Math Blocks: A lingering blue selection ring on Math blocks has been removed, so selection state in the editor is once again accurate

Per-Paragraph Text Alignment: Mobile Study Mode now renders per-row text alignment with full fidelity to the Card Editor. A new ParagraphAlignment enum in ProseMirrorParser carries alignment on every RenderFragment, and CardContentRenderer’s outer VStack was switched to fixed .leading alignment with per-row .frame(maxWidth: .infinity, alignment:) driving placement — so every paragraph aligns independently, matching what you authored on desktop

New ArmedTool type and armedTool slice in editorStore provide a small, reusable foundation for future “click to arm, click to place” tools beyond Math and Code
Removed stale code from the legacy Brain Dump implementation as part of ongoing cleanup
iOS RenderFragment pipeline extended with ParagraphAlignment, finishing the per-paragraph alignment story started in the v0.5.0 rich-text refactor
